Congratulations to Dr Patrick Adelhardt from LEP! He defended very successfully his doctoral thesis entitled „Excitations and quantum criticality of spin systems with long-range interactions“. Long-range interactions in quantum spin systems can lead to fundamentally different and exotic phenomena...

Congratulations to Jonas Leibig who successfully defended his master thesis entitled „Ground-state properties of one-dimensional Dicke-Ising models. Jonas Leibig worked the last year at LEP together with Max Hörmann, Anja Langheld, Andreas Schellenberger, and Kai Phillip Schmidt. He obtained very ni...

Congratulations to Jan Hartmann who successfully defended his Bachelor thesis entitled "Anregungen und Magnetisierung eines räumlich anisotropen Shastry-Sutherland Modell.  Jan worked the last month at the LEP, in particular with Patrick Adelhardt, Antonia Duft, Jan Koziol, and Kai Phillip Schmidt. ...

We are happy that our new publication entitled "Fracton and topological order in the XY checkerboard toric code" just appeared as a letter in Physical Research Research.  A very nice piece of work by LEP members Maximilian Vieweg and Kai Phillip Schmidt. Why is it interesting? 👉 Everyone in Qu...

It was a pleasure to welcome the president Joachim Hornegger of our university at LEP and the FAU Profile Center Light.Matter.QuantumTechnologies  last Semester as part of his series "a cup with the president". Now the corresponding article is online. Check out  https://www.lightmatter.fau.de/202...

New preprint arXiv:2508.05133 entitled “Symmetry breaking and competing valence bond states in the star lattice Heisenberg antiferromagnet”. This work is a nice collaboration with Pratyay Ghosh, Samuel Nyckees, and Frederic Mila from EPF Lausanne and LEP members Jan Alexander Koziol and Kai Phillip ...

End of Juli the concluding meeting of the integrated graduate school of the TRR 306 QuCoLiMa took place in Erlangen. During the meeting several scientific talks by members of the graduate school including (former) LEP members Jan Alexander Koziol, Paul Fadler, and Andreas Schellenberger as well as J...

We are happy that our latest article on disordered quantum magnets has just been published in Physical Review B entitled “Quantum Monte Carlo study of the bond- and site-diluted transverse-field Ising model”. The article is joint work from LEP members Calvin Krämer, Max Hörmann, and Kai Phillip Schm...

Saturday, 28.06.2025, LEP member Kai Phillip Schmidt gave a public talk in the talk series „Moderne Physik am Samstag morgen“ (Modern Physics on Saturday Mornings) at the physics department of FAU Erlangen-Nürnberg which is organized by Florian Marquardt (FAU/MPL). The talk was entitled „Quantum Sci...

Great News! We are happy that our article entitled "Melting of Devil's Staircases in the Long-Range Dicke-Ising Model" has been published in Physical Review B last week. The article is a nice collaboration from LEP members Jan Alexander Koziol, Anja Langheld, and Kai Phillip schmidt. In the artic...
