Bulk Superconductivity driven by Disorder-Induced Delocalization in 4Hb-Ta(SSe)
Lu Chen, Sae-Hee Ryu, Avior Almoalem +10
The unconventional superconductor 4Hb-TaS is a natural heterostructure that can be broadly understood as interleaving Mott-like and metallic layers. We study the properties of…
Mixed-state topological order and the errorfield double formulation of decoherence-induced transitions
Yimu Bao, Ruihua Fan, Ashvin Vishwanath +1
We develop an effective field theory characterizing the impact of decoherence on states with abelian topological order and on their capacity to protect quantum information. The dec…
Gaplessness from disorder and quantum geometry in gapped superconductors
Omri Lesser, Sagnik Banerjee, Xuepeng Wang +3
It is well known that disorder can induce low-energy Andreev bound states in a sign-changing, but fully gapped, superconductor at junctions. Generically, these excitations are…
Stabilization of long-range order in low-dimensional nonequilibrium models
Oriana K. Diessel, Jaewon Kim, Ehud Altman
It is now well established that the Mermin-Wagner theorem can be circumvented in nonequilibrium systems, allowing for the spontaneous breaking of a continuous symmetry and the emer…
