The theorist explored the potential of tensor networks as a tool for describing chiral gapped condensed matter systems. His work showed how methods from quantum field theory could extend the range of applicability of tensor network theory. His results effectively render tensor networks a more complete and powerful theory for condensed matter, allowing them to describe a wider variety of systems using exclusively analytical techniques. more

In his PhD project, Kritsana Srakaew investigated how tunable long-range interactions of Rydberg atoms can be utilised in quantum many-body systems. His research focused on two key settings: subwavelength atomic arrays and itinerant Hubbard systems. His findings deepen our understanding of how Rydberg interactions shape quantum systems, opening new avenues for controlling light-matter interactions and studying complex quantum phases. more

In his dissertation, Julian Wienand studied chaotic quantum systems and their description. His work demonstrated for the first time that such systems can be understood macroscopically as diffusion processes. The model of fluctuating hydrodynamics (FHD), which simplifies the description of complex systems, is therefore also applicable to quantum processes. These results could significantly simplify the analysis of quantum systems. more

Xing-Yan Chen pursued his PhD project in the Quantum Many Body Systems division. His work, supervised by Xin-Yu Luo and Immanuel Bloch, focuses on the creation and manipulation of ultracold molecules. Specifically, he demonstrated a new type of scattering resonances between polar molecules, and used these resonances to bind two molecules into a "supermolecule". more

The physicist from the Department of Laser Spectroscopy at MPQ has measured electronic transitions in deuterium with unprecedented precision. The prize, named after the Nobel Prize winner and pioneer of laser spectroscopy, honours particularly outstanding and ground-breaking dissertations in the field of physics. In his work, Vitaly Wirthl succeeded in measuring a specific energy transition in deuterium, the heavy hydrogen, more precisely than ever before. more
