Weak-pairing higher order topological superconductors

Y Wang, M Lin, TL Hughes - Physical Review B, 2018 - APS
Conventional topological superconductors are fully gapped in the bulk but host gapless
Majorana modes on their boundaries. We instead focus on a new class of superconductors …

Beyond triplet: Unconventional superconductivity in a spin-3/2 topological semimetal

H Kim, K Wang, Y Nakajima, R Hu, S Ziemak… - Science …, 2018 - science.org
In all known fermionic superfluids, Cooper pairs are composed of spin-1/2 quasi-particles
that pair to form either spin-singlet or spin-triplet bound states. The “spin” of a Bloch electron …

Bogoliubov Fermi surfaces: General theory, magnetic order, and topology

PMR Brydon, DF Agterberg, H Menke, C Timm - Physical Review B, 2018 - APS
We present a comprehensive theory for Bogoliubov Fermi surfaces in inversion-symmetric
superconductors which break time-reversal symmetry. A requirement for such a gap …
