Irreducible momentum-space spin structure of Weyl semimetals and its signatures in Friedel oscillations
Andy Knoll, Carsten Timm
Materials that break time-reversal or inversion symmetry possess nondegenerate electronic bands, which can touch at so-called Weyl points. The spinor eigenstates in the vicinity of…

Topological classification of non-Hermitian Hamiltonians with frequency dependence
Maximilian Kotz, Carsten Timm
We develop a topological classification of non-Hermitian effective Hamiltonians that depend on momentum and frequency. Such effective Hamiltonians are in one-to-one correspondence…
