We introduce the notion of nonreciprocal superconductors where inversion and time-
reversal symmetries are broken, giving rise to an asymmetric energy dispersion. We …

Electromagnetic responses in superconductors provide valuable information on the pairing
symmetry as well as physical quantities such as the superfluid density. However, at the …

Determination of the symmetry property of superconducting gaps has been a central issue in
studies to understand the mechanisms of unconventional superconductivity. Although it is …

We study mean-field states resulting from the pairing of electrons in time-reversal broken
fractal Hofstadter bands, which arise in two-dimensional lattices where the unit cell traps …

The possible symmetries of the superconducting pair amplitude is a consequence of the
fermionic nature of the Cooper pairs. For spin-1/2 systems this leads to the SPOT=− 1 …

Superconductors lacking both inversion symmetry and time-reversal symmetry have been
attracting much attention as a platform for exotic superconducting phases and anomalous …

Abstract In recent times, Bogoliubov Fermi surfaces (BFSs) in superconductors (SCs) have
drawn significant attention due to a substantial population of Bogoliubov quasiparticles …

Recently it has been shown experimentally that the superconducting state of FeSe 1− x S x
exhibits Bogoliubov Fermi surfaces for x> 0.17. These Bogoliubov Fermi surfaces appear …

Motivated by the recent discovery of odd-parity multipolar antiferromagnetic order in CeRh 2
As 2, we examine the coexistence of such translation invariant Kramers' degenerate …

We theoretically investigate the thermoelectric response of Bogoliubov Fermi surfaces
(BFSs) generated in a two-dimensional unconventional d-wave superconductor subjected to …
