Theory of Spin-splitter Magnetoresistance in Altermagnets
Tim Kokkeler, Vitaly N. Golovach, F. Sebastian Bergeret
We develop a theory of angular-dependent magnetoresistance (ADMR) in metallic altermagnets coupled to ferromagnetic insulators and establish criteria that distinguish them from con…
Surface States in Strain-Induced Nodal-Line Topological Semiconductors
Vitaly N. Golovach, Alexander Khaetskii
This work explores the topological phase diagram of inverted-band-gap semiconductors under strain and spin-orbit coupling. Using a minimalistic Luttinger Hamiltonian model, we foll…
Weak-anti-localization-to-spin-dependent scattering at a proximity-magnetized heavy metal interface
Hisakazu Matsuki, Guang Yang, Jiahui Xu +9
A change in a materials electrical resistance with magnetic field (magnetoresistance) results from quantum interference effects and, or spin-dependent transport, depending on mater…
Interplay between strain and size quantization in a class of topological insulators based on inverted-band semiconductors
Alexander Khaetskii, Vitaly Golovach, Arnold Kiefer
We consider surface states in semiconductors with inverted-band structures, such as -Sn and HgTe. The main interest is the interplay of the effect of a strain of an arbitrary si…
Quasiparticle density of states and triplet correlations in superconductor/ferromagnetic-insulator structures across a sharp domain wall
Alberto Hijano, Vitaly N. Golovach, F. Sebastián Bergeret
A ferromagnetic insulator (FI) in contact with a superconductor (S) is known to induce a spin splitting of the BCS density of states at the FI/S interface. This spin splitting caus…
Revisiting the physical origin and nature of surface states in inverted-band semiconductors
Alexander Khaetskii, Vitaly Golovach, Arnold Kiefer
We revisit the problem of surface states in semiconductors with inverted band structures, such as -Sn and HgTe. We unravel the confusion that arose over the past decade regardin…
