If you have been always excited about Hermitian and non-Hermitian operators, you want to deepen your (and our) knowledge on quantum materials in interaction with light (or sometimes without), you are not afraid of computers, and you enjoy to work in an agile international team: make your bachelor, your master or even your PhD thesis in the LMCQM group. Contact Michael for further details.

We are a theoretical condensed matter physics research group having fun at the intersection of non-equilibrium many-body physics, quantum materials, and quantum optics. We also simulate atomistic systems with different levels of approximations, and participate in the development of an open source scientific software package which is used all over the world.

We are part of the Institute of Theoretical Solid-State Physics and the Bremen Center for Computational Materials Science.

Multipole Expansion of Atomic Electron Density Fluctuation Interactions in the Density-Functional Tight-Binding Method

Van-Quan Vuong, Bálint Aradi, Anders M. N. Niklasson, Qiang Cui, and Stephan Irle

J. Chem. Theory Comput19, 7592 (2023).

The accuracy of the density-functional tight-binding (DFTB) method in describing noncovalent interactions is limited due to its reliance on monopole-based spherical charge…


Michael awarded with ERC Consolidator Grant

With the ERC Consolidator Grant, he will receive funding of around two million euros. The funding will benefit the CAVMAT research project he is leading, which focuses on new ways of changing matter through light.

Further details in the university's press release.
