Evolution from an acoustic-plasmon-mediated superconductivity to an acoustic-phonon-mediated superconductivity in bilayers
Shuyang Wang, Sankar Das Sarma, Jay D. Sau
Motivated by recent developments in van der Waals heterostructures, we revisit the acoustic plasmon mechanism of superconductivity in bilayer systems composed of a light layer (LL)…
Interaction robustness of the chiral anomaly in Weyl semimetals and Luttinger liquids from a mixed anomaly approach
Shuyang Wang, Jay D. Sau
The chiral anomaly is one of the robust quantum effects in relativistic field theories with a chiral symmetry where charges in chiral sectors appear to be separately conserved. The…
Conventional and practical metallic superconductivity arising from repulsive Coulomb coupling
Sankar Das Sarma, Jay D. Sau, Yi-Ting Tu +1
A concrete question is discussed: Can there be conventional s-wave superconductivity in regular 3D (or 2D) metals, i.e., electrons in a jellium background, interacting via the stan…
Theory of anomalous Hall effect from screened vortex charge in a phase disordered superconductor
Jay D. Sau, Shuyang Wang
Motivated by recent experiments showing evidence for chiral superconductivity in an anomalous Hall phase of tetralayer graphene, we study the relation between the normal state anom…
