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…
Dephasing catastrophe in dimensions: A possible instability of the ergodic (many-body-delocalized) phase
Yunxiang Liao, Matthew S. Foster
In two dimensions (2D), dephasing by a bath cuts off Anderson localization that would otherwise occur at any energy density for fermions with disorder. For an isolated system with…
Response theory of the ergodic many-body delocalized phase: Keldysh Finkel'stein sigma models and the 10-fold way
Yunxiang Liao, Alex Levchenko, Matthew S. Foster
We derive the finite temperature Keldysh response theory for interacting fermions in the presence of quenched disorder, as applicable to any of the 10 Altland-Zirnbauer classes in…
