Scientists at Heidelberg University have achieved a groundbreaking milestone in quantum physics: the creation of a Laughlin fractional quantum Hall state using just two ultracold fermions.
“The whole is greater than the sum of its parts” – this phrase often attributed to Aristotle captures the essence of one of the most intriguing phenomena in nature: emergence. When several parts of a physical system interact, new properties can arise that its single parts do not have on their own. A striking example is the collective behaviour of quantum many-body systems, which can produce novel effects like low-energy excitations carrying a fraction of an electron's charge.
Researchers from the group of STRUCTURES' principal investigator Prof. Selim Jochim at Heidelberg University, in collaboration with Philipp Preiss from LMU Munich, have made significant progress in understanding the emergence of fractional charges. By trapping and spinning a single pair of ultracold lithium-6 atoms in optical tweezers, they replicated the topological properties of this exotic state, previously seen only in bosonic systems. Using a tailored rotation to mimic the influence of a magnetic field, they achieved a strongly correlated atomic state described by physicist Robert Laughlin's wave function for the fractional quantum Hall effect, characterized by its collective and topological nature.
This accomplishment marks a crucial step in the study of emergence of topological phases of matter and paves the way to exploring more complex states, such as quantum Hall ferromagnetism and topological p-wave superconductors.

Prof. Wolfram PerniceMost important research advancement prize honors the experimental work on integrated photonics by Prof. Wolfram Pernice and his team.
We are proud to announce that our member Wolfram Pernice has been awarded the prestigious Gottfried Wilhelm Leibniz Prize of the German Research Foundation (DFG). The award honors his groundbreaking pioneering work on neuromorphic photonic computing, a transformative field at the intersection of physics, computer science, and engineering.
Prof Wolfram Pernice heads the research group Neuromorphic Quantum Photonics at Kirchhoff Institute for Physics and is part of STRUCTURES' Comprehensive Project CP 5: Quantum Systems and Neural Networks: Computation in Physical Structures. The goal of his research in the field of integrated photonics is to develop new methods for information processing and rapid computation using light. By developing nanoscale chip systems, his research has far-reaching implications for artificial intelligence and quantum technologies. The DFG underlines that his interdisciplinary research crosses traditional boundaries; it impacts on various disciplines – from natural sciences to computer science to engineering sciences. “His research results point the way to innovative, sustainable methods for reducing energy consumption of AI computer hardware and still enabling rapid calculations. Furthermore, he is known worldwide as a pioneer in the field of integrated quantum photonics,” the German Research Foundation adds.
The Gottfried Wilhelm Leibniz Prize – the most important research award in Germany – has been awarded annually by the German Research Foundation since 1986. Up to ten prizes can be awarded each year with prize money of 2.5 million euros each. The awards for 2025 go to four female and six male researchers, including Wolfram Pernice. An award also goes to mathematician Prof. Angkana Rüland, a former member of STRUCTURES who did research on applied mathematics at Heidelberg University from 2020 to 2023. The purpose of the Leibniz Programme, established in 1985, is to honor outstanding scientists, to expand their research opportunities and facilitate employment of particularly qualified early-career researchers. The award ceremony will take place on 19 March 2025 in Berlin.

We are delighted to announce that STRUCTURES Professor Astrid Eichhorn has secured one of the prestigious ERC Consolidator Grants by the European Research Council (ERC). This highly competitive grant will support her pioneering research into the quantum nature of gravity, enabling her and her team to deepen our understanding of this fundamental aspect of the universe. Over a period of five years, her project will receive two million euros in funding.
Astrid Eichhorn's research focuses on the quantum properties of space-time and the interplay with the fundamental building blocks of the universe, including elementary particles of the Standard Model of particle physics, dark matter and dark energy. In her ERC-funded project “Probing the Quantum Nature of Gravity at All Scales” (ProbeQG) she aims to primarily explore how to test fundamental theories on the quantum structure of space-time through experiments and observations. The central challenge is that the quantum properties of space-time manifest on tiny length scales – about 17 orders of magnitude below the scales that can be directly examined experimentally by the Large Hadron Collider, the particle accelerator of the European research center CERN. The main idea of the ProbeQG project is to identify “lever arms”. These are systems that translate the effects of quantum gravity on tiny scales into effects that are experimentally accessible. To this end, Prof. Eichhorn and her team want to build a bridge between the theory of asymptotically safe quantum gravity, particle physics, black hole physics and cosmology.
Astrid Eichhorn is a STRUCTURES Professor at the Institute of Theoretical Physics (ITP), where she is heading the Quantum Gravity group. She completed her PhD at the University of Jena, before she pursued a postdoctoral position at Perimeter Institute for Theoretical Physics in Waterloo, and subsequently became a research fellow at Imperial College London. At Heidelberg University she led an Emmy Noether Group on the fundamental quantum structure of space-time and matter from 2016 to 2020. From 2019 she served first as associate professor and from 2023 as full professor at the Centre for Cosmology and Particle Physics Phenomenology at the University of Southern Denmark. In 2024, she returned to Heidelberg, where she was appointed to one of the newly established STRUCTURES Professorships. Prof. Eichhorn's contributions to quantum gravity have earned her recognition as a leading voice in the field.

We are delighted to congratulate our member Dominika Wylezalek, research group leader at the Centre for Astronomy (ZAH) of Heidelberg University, on winning one of the three Klaus-Georg and Sigrid Hengstberger Awards for early-career scientists.
Since 2004, the Klaus-Georg and Sigrid Hengstberger Prize has been awarded annually to excellent early-career scientists at Ruperto Carola. The award comes with a prize money of €12,500 and enables the prizewinners to hold a scientific symposium at the International Academic Forum Heidelberg (IWH).
The symposium led by astrophysicist Dominika Wylezalek will focus on the formation and evolution of galaxies – complex phenomena shaped by intricate interactions between stars, gas, dust, black holes, and supernovae. The symposium, titled “Quo Vadis Galaxy Evolution: How Galaxies Form and Evolve,” is scheduled for June 2025.

We are delighted to congratulate Malek Alhajkhouder, member of the Young Researchers Convent (YRC) at STRUCTURESon being awarded the Rhodes Scholarship in recognition of his academic achievements in physics. Malek Alhajkhouder completed his master's degree with a focus on particle physics at Heidelberg University, where he conducted his master's thesis under the supervision of Prof. Jan M. Pawlowski at the Institute for Theoretical Physics.
Originally from Damascus, Syria, Malek Alhajkhouder is a physicist and former scholar of the Heinrich Böll Foundation. His experiences growing up in the Middle East and North Africa (MENA) region and living across multiple countries have profoundly influenced his personality. He further enriched his international academic journey with a semester at La Sapienza University in Rome. At Oxford, Malek plans to pursue a DPhil (PhD) in Theoretical Physics and continue his research, seeking answers to questions regarding elementary particles. In addition, he aims to inspire more students, particularly from the Levant, to engage in fundamental research.
The Rhodes Scholarship is a fully funded, full-time, postgraduate award supporting students from around the world to study at the University of Oxford.
