Exotic superconducting states in altermagnets
Kirill Parshukov, Andreas P. Schnyder
The interplay between magnetism and superconductivity is one of the central topics of condensed matter physics, which has recently been put into new light by the discovery of alter…
Weak Supertopology
Kirill Parshukov, Moritz M. Hirschmann, Andreas P. Schnyder
Crystal symmetries can enforce all bands of a material to be topological, a property that is commonly referred to as ``supertopology". Here, we determine the symmetry-enforced $\ma…
Tunable Octdong and Spindle-Torus Fermi Surfaces in Kramers Nodal Line Metals
Gabriele Domaine, Moritz H. Hirschmann, Kirill Parshukov +9
It has recently been proposed that all achiral non-centrosymmetric crystals host so-called Kramers nodal lines, which are doubly degenerate band crossings connecting time-reversal…
Topological responses from gapped Weyl points in 2D altermagnets
Kirill Parshukov, Raymond Wiedmann, Andreas P. Schnyder
We study the symmetry requirements for topologically protected spin-polarized Weyl points in 2D altermagnets. The topology is characterized by a quantized -Berry phase and the…
