Recent progress on superconductors with time-reversal symmetry breaking

SK Ghosh, M Smidman, T Shang… - Journal of Physics …, 2020 - iopscience.iop.org
Superconductivity and magnetism are adversarial states of matter. The presence of
spontaneous magnetic fields inside the superconducting state is, therefore, an intriguing …

Topological transition from nodal to nodeless Zeeman splitting in altermagnets

RM Fernandes, VS De Carvalho, T Birol, RG Pereira - Physical Review B, 2024 - APS
In an altermagnet, the symmetry that relates configurations with flipped magnetic moments is
a rotation. This makes it qualitatively different from a ferromagnet, where no such symmetry …

Tuning the parity mixing of singlet-septet pairing in a half-Heusler superconductor

K Ishihara, T Takenaka, Y Miao, Y Mizukami… - Physical Review X, 2021 - APS
In superconductors, electrons with spin s= 1/2 form Cooper pairs whose spin structure is
usually singlet (S= 0) or triplet (S= 1). When the electronic structure near the Fermi level is …

Experimental consequences of Bogoliubov Fermi surfaces

CJ Lapp, G Börner, C Timm - Physical Review B, 2020 - APS
Superconductors involving electrons with internal degrees of freedom beyond spin can have
internally anisotropic pairing states that are impossible in single-band superconductors. As a …

Unconventional superconductivity in Y5Rh6Sn18 probed by muon spin relaxation

A Bhattacharyya, D Adroja, N Kase, A Hillier… - Scientific reports, 2015 - nature.com
Conventional superconductors are robust diamagnets that expel magnetic fields through the
Meissner effect. It would therefore be unexpected if a superconducting ground state would …
