Robin Krill successfully defended his master project entitled "Quantum Monte Carlo Simulations for Extended Bose-Hubbard Models" at the University of the Saarland (UdS). He has been jointly supervised by Giovanna Morigi (UdS) and Kai Phillip Schmidt from LEP. In his thesis he developped and applied ...

A team from Erlangen successfully participated in the German Physicists' Tournament (GPT) and reached the final. The team finished 3rd after teams from Aachen and Munich. The GPT 2025 took place in Heidelberg. The GPT is a competition where students have to work on open physics problems. At the t...

New publication entitled „Quantum-critical and dynamical properties of the XXZ bilayer with long-range interactions“ in Physical Review B (see https://journals.aps.org/prb/abstract/10.1103/PhysRevB.111.024409). Nice collaboration between LEP members Patrick Adelhardt, Antonia Duft, and Kai Phillip S...

Check out the new preprint 2412.17495 by LEP members Antonia Duft, Patrick Adelhardt, and Kai Phillip Schmidt entitled „Quantum Phase Diagram of the Bilayer Kitaev-Heisenberg Model“. Great collaboration with Elahe Samimi and Saeed S. Jahromi from Institute for Advanced Studies in Basic Sciences, Zan...

Colloidal particles can form network-like structures that slowly change in time. The dynamics of such gels varies a lot such that some gels are fluid-like while others are solid. However, the structural differences might be small . In a new article we show that neural networks nevertheless can di...

On 09.12. we had the great PhD defense of Matthias Walther under the supervision of Kai Phillip Schmidt. His thesis is entitled „Effective models for interacting Spin waves in two-dimensional quantum antiferromagnets“. In particular, he developed non-perturbative continuous similarity transformation...

Nothing works as it should in the Physics Department, because … Physics has disappeared. How could this happen? Who is responsible for the disappearance? What a great show! On  December 3, 2024 the Christmas lecture 2024 of the physics department took place with more than 700 spectators. This yea...

On 06.12. we had the great PhD defense of Matthias Mühlhauser under the supervision of Kai Phillip Schmidt. His thesis is entitled „Graph decomposition techniques for quantum spin systems with multi-spin interactions“. In particular, he developed hypergraph expansions for quantum lattice models ...

Check out the new preprint 2411.19051 by LEP members Max Vieweg and Kai Phillip Schmidt entitled "Fracton and topological order in the XY checkerboard toric code". The conventional 2D toric code is the most paradigmatic, simplest, and exactly solvable model displaying topological order, which ha...
