Non-Hermitian topological devices with Chern insulators
Kyrylo Ochkan, Michael Wissmann, Louis Veyrat +9
Multi-terminal topological devices are a new generation of electronic devices with quantized properties robust against imperfections. In magnetic topological insulators, dissipatio…
Axion electrodynamics of Weyl superconductors with broken time-reversal symmetry
Vira Shyta, Jeroen van den Brink, Flavio S. Nogueira
The low-energy effective description of Weyl semimetals is defined by the axion electrodynamics, which captures the effects arising due to the presence of nodes of opposite chirali…
Topological nodal -wave superconductivity in PtBi
Susmita Changdar, Oleksandr Suvorov, Andrii Kuibarov +11
Most superconducting materials are well-understood and conventional in the sense that the pairs of electrons that cause the superconductivity by their condensation have the highest…
Chiral magnetic excitations and domain textures of g-wave altermagnets
Volodymyr P. Kravchuk, Kostiantyn V. Yershov, Jorge I. Facio +5
Altermagnets (AMs) constitute a novel class of spin-compensated materials in which opposite-spin sublattices are connected by a crystal rotation, causing their electronic iso-energ…
Influence of pressure on properties of multi-gap type-I superconductor BeAu
Rustem Khasanov, Riccardo Vocaturo, Oleg Janson +7
We report on studies of the superconducting and normal state properties of the noncentrosymmetric superconductor BeAu under hydrostatic pressure conditions. The room-temperature eq…
Curvature induced magnetization of altermagnetic films
Kostiantyn V. Yershov, Olena Gomonay, Jairo Sinova +2
We consider a thin film of -wave altermagnet bent in a stretching-free manner and demonstrate that gradients of the film curvature induce a local magnetization which is approxim…
