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)…
Superconductivity from phonon-mediated retardation in a single-flavor metal
Yang-Zhi Chou, Jihang Zhu, Jay D. Sau +1
We study phonon-mediated pairings in a single-flavor metal with a tunable Berry curvature. In the absence of Berry curvature, we discover an unexpected possibility: -wave superc…
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…
Topologically protected emergent Fermi surface in an Abrikosov vortex lattice
Songyang Pu, Jay D. Sau, Rui-Xing Zhang
We show that a three-dimensional (3D) fully gapped type-II superconductor can feature emergent in-gap Fermi surfaces of Caroli-de Gennes Matricon (CdGM) quasiparticles in the prese…
Phase diagram and excitations of a Shiba molecule
N. Y. Yao, C. P. Moca, I. Weymann +4
We analyze the phase diagram associated with a pair of magnetic impurities trapped in a superconducting host. The natural interplay between Kondo screening, superconductivity and e…
Odd-parity superconductivity from phonon-mediated pairing: Application to CuBiSe
P. M. R. Brydon, S. Das Sarma, Hoi-Yin Hui +1
Motivated by the proposed topological state in CuBiSe, we study the possibility of phonon-mediated odd-parity superconductivity in spin-orbit coupled systems with time-…
