Bound on resistivity in flat-band materials due to the quantum metric
Johannes Mitscherling, Tobias Holder
The quantum metric is a central quantity of band theory but has so far not been related to many response coefficients due to its nonclassical origin. However, within a newly develo…

Non-Hermitian band topology from momentum-dependent relaxation in two-dimensional metals with spiral magnetism
Johannes Mitscherling, Walter Metzner
We study the emergence of non-Hermitian band topology in a two-dimensional metal with planar spiral magnetism due to a momentum-dependent relaxation rate. A sufficiently strong mom…

Electrical Conductivity in Quantum Materials
Johannes Mitscherling
In recent years, there is an increasing interest in transport phenomena that are fundamentally linked to the presence of multiple bands. In this thesis, we develop, discuss, and ap…
