International re­search team including STRUC­TURES member Ralf Klessen re­ceives computing time for simulating the behaviour of cosmic gases and plasmas during star formation

A Swiss-German interdisciplinary re­search team hopes to unlock the secrets of star formation using Europe’s fastest computer – the LUMI-G supercomputer in Kajaani (Finland) run by an international consortium. The researchers, including Hei­del­berg astrophysicists, aim to simulate the behaviour of gases and plasmas using a new simulation code called SPH-EXA. Project partner and STRUC­TURES member Prof. Dr Ralf Klessen of Hei­del­berg Uni­ver­si­ty’s Centre for Astronomy (ZAH) anticipates groundbreaking insights for his own research: “With our simulations we are pursuing an approach that takes the particles of gases and plasmas into account to describe the movement of fluid elements in space. This allows us to make statements about the chaotic behaviour of turbulent streams or to better capture aspects of the transition from orderly to chaotic phases of the stream.” The computer experiment thereby opens up new avenues to better understand the formation of stars and star clusters in the turbulent multi-phase interstellar medium of galaxies such as our Milky Way.

Re­search Awards: Highlighting Two Special STRUC­TURES Breakthroughs

A curved and expanding spacetime has been simulated in a Bose-Einstein condensate.

Curved Spacetime in the Lab

We are deligthed to announce that re­search from STRUCTURES' Comprehensive Project (CP 4: Quan­tum Structure and Dynamics) carried out by Celia Viermann and the group of Markus Oberthaler, in collaboration with external member Stefan Flörchinger, has made this year's Physics World list of Top 10 Breakthroughs of the Year 2023. In their laboratory experiment, the researchers have succeeded in realizing a quan­tum simulation of a curved and expanding spacetime. Within an ultracold quan­tum gas, they were able to simulate an entire family of curved universes that can be manipulated, allowing to investigate and comapre different cosmological scenarios with the predictions of a quan­tum field theo­re­ti­cal model (see also this earlier news item for more details). The re­search results were published in Nature (see Viermann et al., 2022).

Topological analysis of a vector field with discontinuity exhibiting sliding flow.
Visualization of Discontinuous Vector Field Topology

We are delighted to announce that a study from STRUCTURES' CP 6 (Networks and Ma­chine Learning) carried out by Egzon Miftari, Filip Sadlo and Daniel Durstewitz has been awarded one of the prestigious Best Paper Award of the IEEE VIS 23, the premier conference for visualization and visual analytics. The award is considered one of the most renowned awards for publications in this field of research. In their work, the researchers extend vector field topology to discontinuous but piecewise-continuous vector fields, by providing extraction techniques for Filippov systems and extending these systems with non-unique transport. This enables visualizing and exploring the behaviors of complex flow with discontinuities, which is extremely important in many engineering and application fields. An overview of this work can be found in this year's CP 6 project report by Egzon Miftari and Filip Sadlo featured in STRUC­TURES News (October 2023), page 3.

Prof. Guy Wolf to Join STRUC­TURES and IWR as Humboldt Re­search Fellow in 2024

Prof. Guy Wolf (MILA / Université de Montréal, Canada, picture used with kind permission)

We are delighted to announce that Prof Guy Wolf, CIFAR AI Chair at MILA, Montreal, and Associate Pro­fes­sor at Université de Montréal, will be joining Hei­del­berg Uni­ver­si­ty for a re­search stay at the Interdisciplinary Center for Scientific Computing (IWR) and STRUC­TURES in early 2024, as part of the competitive Humboldt Re­search Fellowship Programme.

The Humboldt Re­search Fellowship enables outstanding researchers to conduct their own re­search in collaboration with a host at a German re­search institution of their choice, fostering a dynamic exchange of knowledge and expertise. During his stay in Hei­del­berg, Prof Wolf will also hold a one-week compact course for MSc and PhD students.

Prof Wolf's re­search focuses at the intersection of ma­chine learning, data science and applied mathematics. He is particularly interested in data mining methods utilizing manifold learning and deep geometric learning, as well as applications for exploratory analysis of biomedical data. His multidisciplinary approach integrates ma­chine learning, signal processing, and applied mathematics to discover patterns, dynamics, and structures in large high-dimensional datasets.

We eagerly welcome Prof Wolf and anticipate the fruitful collaborative exchange!

We are happy to announce the next Scientific Ma­chine Learning event from the series “Ma­chine Learning Galore!”, which will take place on January 18 from 4:30 to 6:00 pm in INF 205 Mathematikon (5th floor). The event will include various lab presentations and science talks:

Ma­chine Learning galore! - Programme:
  • Lab presentations:
    • Tristan Bereau, Fred Hamprecht, Caroline Heneka
  • Rocket Science:
    • Tristan Bereau: Ma­chine learning representation for molecular dynamics
    • Roman Remme (Hamprecht lab): Ma­chine Learning meets Density Functional Theory
    • Lara Alegre (Heneka lab): Ma­chine Learning for large radio surveys

To help plan the catering, please register for free until Jan 15 via this webpage.

Scientific Ma­chine Learning is a joint initiative from IWR and STRUC­TURES to foster interactions within and development of the local ma­chine learning community. Its portal, http://mlai.uni-heidelberg.de summarizes the many relevant events and news from across campus that would otherwise remain scattered across single institutions or fields. The goal of the initiative aligns with the STRUC­TURES Cluster of Excellence's objective of driving re­search into the fundamental understanding of current and future ma­chine learning, and with IWR’s aim to leverage ma­chine learning to enable the solution of long-standing problems in the natural and life sciences, the engineering sciences, as well as the humanities.
