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…
Stability of Bogoliubov Fermi Surfaces within BCS Theory
Ankita Bhattacharya, Carsten Timm
It has recently been realized that the gap nodes of multiband superconductors that break time-reversal symmetry generically take the form of Fermi surfaces of Bogoliubov quasiparti…
Helical Topological Superconducting Pairing at Finite Excitation Energies
Masoud Bahari, Song-Bo Zhang, Chang-An Li +4
We propose helical topological superconductivity away from the Fermi surface in three-dimensional time-reversal-symmetric odd-parity multiband superconductors. In these systems, pa…
Majorana flat bands at structured surfaces of nodal noncentrosymmetric superconductors
Clara J. Lapp, Carsten Timm
Surfaces of nodal noncentrosymmetric superconductors can host flat bands of Majorana modes, which provide a promising platform for quantum computation if one can find methods for m…
Classification of Weyl points and nodal lines based on magnetic point groups for spin- quasiparticles
Andy Knoll, Carsten Timm
Symmetry-protected topological semimetals are at the focus of solid-state research due to their unconventional properties, for example, regarding transport. By investigating local…
