  New Podcast Episode: Exzellent Erklärt - Spitzenforschung für alle

  Research: First dormant black hole found outside the Milky Way

An international research team under participation of STRUCTURES member Fabian Schneider discovered a “dormant” black hole in a binary-star system outside our galaxy. These black holes are very difficult to find because they do not emit X-ray radiation.

In their study, published in Nature Astronomy, the researchers reported the first discovery of a ‘dormant’ stellar-mass black hole, VFTS243, outside the Milky Way galaxy, based on observations with ESO's Very Large Telescope (VLT). Stellar-mass black holes form when massive stars collapse under their own gravity at the end of their lives. If this happens in a binary system, the resulting black hole will be orbiting a luminous companion star. Such black holes often accrete material from their companion and emit powerful X-rays, but a “dormant” black hole does not. Astronomers suspect that many more dormant black holes exist than previously thought. The team also found that the star that gave rise to VFTS243 disappeared without evidence of a strong supernova explosion, indicating a ‘direct-collapse’ scenario. The new results have significant implications for the origin of black-hole mergers in the cosmos.

Millennium Prize Problems Mathfest: Celebrating the Poincaré Conjecture (July 2022)

In July, we proudly present two talks in Heidelberg on the Poincaré Conjecture, one of the seven famous, complex “Millennium Prize Problems” defined by the Clay Mathematics Institute in 2000. On July 15 and 22, respectively, Prof. Dr. Markus Banagl (Uni Heidelberg) and Prof. Dr. Sebastian Hensel (LMU Munich) will give insights into this intriguing subject and recent developments in the field. After the talk on July 22, there will be the opportunity to talk to the lecturer and other scientific experts and to participate in a hands-on exploration of geometry and topology at the Heidelberg Experimental Geometry Lab (HEGL). These events are part of a nationwide Millennium Prize Problems celebration. The solution to each of these problems carries a prize of 1 million USD. Among them, only the Poincaré conjecture has been fully resolved. Established by Henri Poincaré in 1904 and proved by Grigori Perelman in 2003, it states that every finite three-dimensional space without boundary, on whose surface every loop can be continuously contracted to a point, must have the form of a three-dimensional sphere.

Details on the programme can be found on the event page of the Research Station Geometry & Dynamics.
Please also see the associated press release (German).

  Research: Bubbly structure of gas in the Milky Way

An international group of astronomers under participation of STRUCTURES member Ralf Klessen found the imprint of the bubbles produced by the explosion of dying stars in the structure of the gas that pervades our galaxy.

An international researcher team under participation of STRUCTURES scientists has found the imprint of bubbles produced by supernova explosions in the structure of the gas that pervades our Galaxy. They made this discovery by applying artificial intelligence (AI) methods to data from the HI4PI survey, the most detailed all-sky map of atomic hydrogen in the Galaxy to date. The scientists analysed filamentary structures in the emission of atomic hydrogen and found that their orientation with respect to the Galactic plane changes progressively with radius, indicating a similar distribution of atomic gas as in nearby spiral galaxies. The study revealed that filamentary structures preserved a record of dynamical processes induced by ancient supernova explosions and the rotation of the Galaxy. The new results are an important step in understanding the process responsible for galaxy-scale star formation.

  Research: Collective movement of pathogens largely determined by physical principles

STRUCTURES member Ulrich Schwarz examines how physical properties of malaria parasites can influence their individual and collective dynamics, as part of an interdisciplinary research team.

The disease of malaria is triggered by single-celled parasites that accumulate in large groups in the salivary glands of mosquitoes before transmission to human beings. In an interdisciplinary study, the research teams led by Prof. Dr Friedrich Frischknecht (malaria research), Prof. Dr Karl Rohr (biomedical image analysis) and Prof. Dr. Ulrich Schwarz (physics of complex biosystems) have set the pathogens in motion and studied their collective dynamics. The researchers discovered that malaria parasites can migrate in large vortices when extracted by means of appropriate experimental preparation. To understand these phenomena the acquired image data were analysed quantitatively using cutting-edge methods of image processing. Through so-called agent-based computer simulations, it was possible to precisely identify the parameters that explain the experimental observations. The teams observed emerging properties of the collective migration, which arise because the movement of the individual pathogens is converted into elastic energy that is stored in the vortex. “Our new model system offers the opportunity to better understand the physics of collectives with elastic properties and perhaps render them usable for technical applications in the future,” explains Ulrich Schwarz.

“Welt der Physik” Podcast with Prof. Ulrich Schwarz on the Physics of Cells

“A cell is the smallest unit of life, in a certain sense the elementary particle of biology” (Ulrich Schwarz). Every living being is made up of cells. The human body for instance consists of over 10¹³ different cells, which are divided into more than 200 different cell types. In order to understand the complex processes in cells, researchers approach them not only from the biological but also from the physical side. In the new episode of Welt der Physik's podcast, Ulrich Schwarz (ITP, STRUCTURES Heidelberg) explains how much physics is in cells. The podcast is in German.

HEGL Community Seminar May 2

We cordially invite you to attend the Heidelberg Experiment Geometry Lab (HEGL) Community Seminar talk by Sean Lawton on May 2 at 3pm:

Title: Dynamics, Finite Fields, and Character Varieties: A Geometry Lab Project Working!
Abstract: In 2014, the Mason Experimental Geometry Lab (MEGL) was founded at George Mason University (GMU). During Fall and Spring of that year, MEGL obtained funding, space, equipment, and participants. In Summer 2015, the first research (and outreach) projects began. One of the first projects explored dynamics on the finite field points of certain algebraic varieties. This project continued every semester and summer until Fall 2018. In addition to interesting conjectures with substantial data to support them and 1000’s of lines of code generating said data, the project created awesome visualizations (images and 3D prints), a GMU-College of Science research award, an undergraduate honors thesis, a PhD thesis, a community of mathematicians (11 student participants, most in PhD programs or in professional scientific positions), and many fond memories. This talk is about that story.

The Seminar will take place online via Zoom. Contact HEGL or join the HEGL Mailing List to get the Zoom coordinates. More information can be found at the HEGL seminar website.

Symposium on Computational Astrophysics May 5 2022

The symposium on Computational Astrophysics will take place on May 5, 2022 in hybrid form. Lectures will be held in attendance for invited guests only but will also be broadcast via ZOOM.

Reality and probability: from atoms to bacteria and the Earth climate

We cordially invite you to attend the talk by Lamberto Rondoni (Politechnico di Torino) on Reality and probability: from atoms to bacteria and the Earth climate on Friday April 22 at 4.00pm at EMBL, Large Operon.

Registration is no longer required, but it is still mandatory to wear FFP2 masks in seminar rooms. Online access via Zoom: Meeting ID: 910 5345 7980, Passcode: 449594

Abstract: Probability is arguably the most effective mathematical tool that all sciences use. However, probability is not reality, and one should be aware of the relations between them, in order to avoid errors, and actually develop useful predictive theories. In this lecture, I will invite the audience and myself to ponder the matter, illustrating various notions probability and giving examples of how statistical physics understands thermodynamic phenomena. I will then discuss success and failures in the use of probabilities in Physics, and will conclude mentioning some applications of biological and geophysical interest. .

“Welt der Physik” Podcast on Emergence with Manfred Salmhofer

“The whole is greater than the sum of its parts.” This phrase, often attributed to Aristotle, is how one could describe one of the most fascinating, complex properties of nature: Emergence. When several parts of a physical system – whether atoms, birds or stars – interact with each other, new properties can be observed that its single parts do not have on their own. This phenomenon is the focus of the new episode by “Welt der Physik”'s podcast “Emergenz”, in which Manfred Salmhofer from STRUCTURES explains how such emergent properties arise and what role they play in physics.

The podcast is in German and available at the “Welt der Physik” webpage:

Welt der Physik: Folge 330 – Emergenz (in German, Feb. 10, 2022).

NEW DATE: Ruperto Carola Lecture Series STRUCTURES: „Strukturen in der Musik Johann Sebastian Bachs“ on February 7, 2022

We are delighted to announce that Prof. Dr. Andreas Kruse's talk on „Strukturen in der Musik Johann Sebastian Bachs“ will take place on February 7 at 7:30 pm at the Aula der Neuen Universität (Access limited to 2G+, FFP-2 mask mandatory).
The talk, which will be in German, focuses on structure in compositions by Johann Sebastian Bach, explaining the term “structure” in music by the example of Viennese Classicism and analyzing themes and motifs of single works by Bach, before addressing the compositional technique of the fugue. Prof. Dr. Andreas Kruse is expert on music, author of the book „Die Grenzgänge des Johann Sebastian Bach“ and Senior professor distinctus at Heidelberg University.

The event will take place as part of the Ruperto Carola Lecture Series (Ruperto Carola Ringvorlesung) STRUCTURES, which focuses on the emergence and description of structures in mathematics and physics, human society, the human body, literature and music. The lecture series is organized by Matthias Bartelmann, STRUCTURES member, and Manfred Salmhofer, speaker of STRUCTURES.

New Podcast Episode: Exzellent Erklärt - Spitzenforschung für alle (7)

STRUCTURES Member Lauriane Chomaz receives ERC Starting Grant

Two outstanding Heidelberg-based early-career researchers – Junior Professor Dr Lauriane Chomaz and Dr Ganna Gryn’ova – have each been awarded an ERC Starting Grant, which is a high amount of funding from the European Research Council (ERC). Prof. Chomaz, an experimental physicist at Heidelberg University, will receive approximately 1.5 million euros for her research work on two-dimensional dipolar quantum gases. The ERC will likewise endow Dr Gryn’ova with around 1.5 million euros for a project on the design and modelling of functional organic materials. The computational chemist from the Heidelberg Institute for Theoretical Studies (HITS) also does research at the Interdisciplinary Center for Scientific Computing (IWR) of Ruperto Carola. The funding has been granted for a period of five years.

Lauriane Chomaz’s research project to be funded with the ERC Starting Grant is called “Two-dimensional Dipolar Quantum Gases: Fluctuations and Orders” (2DDip). In it, she addresses the question of how matter orders itself under extreme conditions – in two-dimensional space and in the presence of competing long-range and short-range atomic interactions – and how the resultant order changes under the effect of quantum and thermal fluctuations. With the assistance of an innovative experimental apparatus, the scientist will, for the first time, generate ultra-cold quantum gases from dysprosium atoms in an effective two-dimensional space. Dysprosium is a rare earth and exhibits the highest magnetic moment of all natural stable chemical elements. By examining different states of these magnetic gases, Prof. Chomaz wants to gain new insights into hitherto unexplored, exotic states of matter, their respective orders, ordering mechanisms, and their fluctuations. The physicist hopes that her research will help to answer open questions on two-dimensional ordering in the presence of long-range atomic interactions, and to open up new research avenues.

After graduating in quantum physics, Lauriane Chomaz gained her doctorate in 2014 with a study of Bose gases in reduced dimensions at the École normale supérieure in Paris (France). She then continued her research as a post-doc at the University of Innsbruck (Austria). For that she received a Marie Skłodowska-Curie Fellowship from the European Commission and was admitted to the Elise Richter Programme of the Austrian Science Fund (FWF). In 2021 she joined Heidelberg University as a tenure-track professor. Prof. Chomaz is part of the STRUCTURES Cluster of Excellence with her newly formed “Quantum Fluids” research group at the Institute for Physics. She is also a member of Heidelberg University’s Collaborative Research Centre 1225 “Isolated Quantum systems and Universality under extreme conditions” (ISOQUANT).

Research: Solving Complex Learning Tasks in Brain-Inspired Computers

STRUCTURES members Andreas Baumbach, Akos Ferenc Kungl, Johannes Schemmel and Mihai Petrovici develop a new training approach for spiking neural networks with their co-workers.

Developing a machine that processes information as efficiently as the human brain has been a long-standing research goal towards true artificial intelligence. The interdisciplinary research team at Heidelberg University and the University of Bern (Switzerland) led by Mihai Petrovici is tackling this problem with the help of biologically-inspired artificial neural networks. Spiking neural networks, which mimic the structure and function of a natural nervous system, represent promising candidates because they are powerful, fast, and energy-efficient. One key challenge is how to train such complex systems. The German-Swiss research team has now developed and successfully implemented an algorithm that achieves such training.

ELLIS LIFE HEIDELBERG RESEARCH UNIT

STRUCTURES members Carsten Rother and Ullrich Köthe participate in the European Laboratory for Learning and Intelligent Systems.

The great potential of artificial intelligence (AI) and machine learning for the life sciences – from basic research in biology to medical applications – has to date largely been neglected.
To leverage that potential in future, researchers from Heidelberg University, the German Cancer Research Center, and the European Molecular Biology Laboratory have founded a new research unit. It aims to support AI research in the life sciences and forge international links with activities in Heidelberg. The unit is part of the European Laboratory for Learning and Intelligent Systems (ELLIS). ELLIS Life Heidelberg will initially be funded by the founding institutions for five years.

Physics of the Quark-Gluon Plasma with Mauricio Martinez Guerrero

Title: Initial state fluctuations of QCD conserved charges in high energy nuclear collisions
Abstract: We initialize the Quantum Chromodynamic conserved charges of baryon number, strangeness, and electric charge arising from gluon splitting into quark-antiquark pairs for the initial conditions of relativistic heavy-ion collisions. A new Monte Carlo procedure that can sample from a generic energy density profile is presented, called Initial Conserved Charges in Nuclear Geometry (ICCING), based on quark and gluon multiplicities derived within the color glass condensate (CGC) effective theory. We find that while baryon number and electric charge have nearly identical geometries to the energy density profile, the initial strangeness distribution is considerable more eccentric and is produced primarily at the hot spots corresponding to temperatures of T≳ 400T ≳ 400 MeV for PbPb collisions at √s N N = 5.02 TeV.

STRUCTURES JOUR FIXE: Heidelberg, Online Seminar.

Friday, July 24th, 2020.

13:30h Minkowski Functionals as Comprehensive Shape Descriptors in Physics“. (Michael A. Klatt, Princeton University, USA).

'Almost a PhD' lecture Series.

Upcoming talk: Monday, July 20, 18:15, Linda Shen: Universelle Dynamik & Thermalisierung in isolierten Quantensystemen.
The talk will be in German this time, as this will be the language of Linda's defence.

About the 'Almost a PhD' lecture series:
In the 'almost a PhD' talks, PhD students shortly before their defence can practice their PhD talk. The presentation will be followed by questions and if wanted a short round of feedback. In this format PhD candidates benefit by practising their talk in front of a live audience and listeners are presented with understandable and hopefully high quality talks about a broad variety of current research topics. And if you are currently in your PhD yourself, you can collect ideas for your own talk in the future!
After the talk is finished and all questions are answered we would love to invite everyone to a virtual get-together. Grab a beer or snacks in front of your computer and have an informal discussion or chat.
If your defence is coming up and you are keen to practice your talk yourself, write us a mail with your topic and your preferred date. We will supply you with a 'drawing pad' that can be connected to a computer, to simulate an actual blackboard presentation. Speakers can borrow one of these pads and use it for their talk.
