Stabilizing fluctuating spin-triplet superconductivity in graphene via induced spin-orbit coupling

JB Curtis, NR Poniatowski, Y Xie, A Yacoby… - Physical Review Letters, 2023 - APS
A recent experiment showed that a proximity-induced Ising spin-orbit coupling enhances the
spin-triplet superconductivity in Bernal bilayer graphene. Here, we show that, due to the …

Boundary criticality of the O (N) model in d= 3 critically revisited

MA Metlitski - SciPost Physics, 2022 - scipost.org
It is known that the classical O (N) model in dimension d> 3 at its bulk critical point admits
three boundary universality classes: the ordinary, the extra-ordinary and the special. For the …

Half-quantum vortices in an antiferromagnetic spinor Bose-Einstein condensate

SW Seo, S Kang, WJ Kwon, Y Shin - Physical Review Letters, 2015 - APS
We report on the observation of half-quantum vortices (HQVs) in the easy-plane polar phase
of an antiferromagnetic spinor Bose-Einstein condensate. Using in situ magnetization …
