Research Group: Correlated Electrons and Topology

Welcome to our group webpage!  We focus on theoretical and numerical studies of condensed matter physics. Below you find links to the research and teaching activities of our group.

What's new?

• 17.05.2022 -- Congratulations to Hua-Chen Zhang for the successful PhD defense at his home institute (Institute of Physics, Chinese Academy of Sciences; supervisor: Prof. Tao Xiang)! The title of his thesis is Quantum many-body model wave functions based on conformal field theories. Hua-Chen will take up a postdoc position at Prof. Anne Nielsen's group (Aarhus University, Denmark) in July 2022.
• 11.05.2022 -- Invited talk at the Asian-European workshop on SU(N) physics in condensed matter and cold atoms (link). Title of the talk: Collapsing Schrödinger’s cat: application of anyon eigenbasis in DMRG; see slides.

• 28.04.2022 -- Joint work with Hui-Ke Jin (TUM), Rong-Yang Sun (Kavli ITS -> RIKEN) and Yi Zhou (IOP, CAS) on Unveiling a critical stripy state in the triangular-lattice SU(4) spin-orbital model is published in Sci. Bull. (see link). Short summary: We provide numerical evidence that the SU(4) Kugel-Khomskii model on the triangular lattice has a critical stripy ground state, which preserves the SU(4) symmetry but breaks the translational symmetry by doubling the unit cell along one of the lattice vector directions.

• 07.03.2022 -- Anton Hulsch joins our group to work on his Bachelor thesis. Welcome!
• 06.03.2022 -- In SoSe2022, we will offer a specialized lecture on Many Body Theory in Condensed Matter. The course information will be continuously updated in this webpage.
