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 ...

Great collaboration with Elahe Samimi and Saeed S. Jahromi from Institute for Advanced Studies in Basic Sciences, Zan...

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...

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...

The Faculty of Sciences has awarded Kai Phillip Schmidt with a Teaching Award 2024. He was nominated by the physics students of our department for his teaching of Theoretical Physics III (Quantum Mechanics) and Rechenmethoden der Physik for first-year students. The price was hand over by our dean Jü...

Last week, the TRR 306 QuCoLiMa held its annual meetings at Kloster Banz, Bad Staffelstein, with many participants from the team of Kai Phillip Schmidt (kps_lab). RTG School: October 6 – 8 Annual Meeting: October 8 – 11 Besides interesting talks and posters from the subprojects, there was...

Harald Leiser from the team of Kai Phillip Schmidt did a great job yesterday in his master colloquium entitled „One quasi-particle properties of 1d quantum spin-systems by non-perturbative linked-cluster expansions“. The master project was done over the past year in close collaboration with Max Hörm...
