Critical Percolation Without Fine Tuning on the Surface of a Topological Superconductor
Sayed Ali Akbar Ghorashi, Yunxiang Liao, Matthew S. Foster
We present numerical evidence that most two-dimensional surface states of a bulk topological superconductor (TSC) sit at an integer quantum Hall plateau transition. We study TSC su…
Topological superconductivity of spin-3/2 carriers in a three-dimensional doped Luttinger semimetal
Bitan Roy, Sayed Ali Akbar Ghorashi, Matthew S. Foster +1
We investigate topological Cooper pairing, including gapless Weyl and fully gapped class DIII superconductivity, in a three-dimensional doped Luttinger semimetal. The latter descri…
Disorder-enhanced topological protection and universal quantum criticality in a spin-3/2 topological superconductor
Sayed Ali Akbar Ghorashi, Seth Davis, Sage B. Brooks +1
We study the Majorana surface states of higher-spin topological superconductors (TSCs) that could be realized in ultracold atomic systems or doped semimetals with spin-orbit coupli…
