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…
Intravalley spin-polarized superconductivity in rhombohedral tetralayer graphene
Yang-Zhi Chou, Jihang Zhu, Sankar Das Sarma
We study the intravalley spin-polarized superconductivity in rhombohedral tetralayer graphene, which has been discovered experimentally in Han arXiv:2408.15233. We constr…
Fractional quantum anomalous Hall effect in rhombohedral multilayer graphene with a strong displacement field
Ke Huang, Sankar Das Sarma, Xiao Li
We investigate the fractional quantum anomalous Hall (FQAH) effect in rhombohedral multilayer graphene (RnG) in the presence of a strong applied displacement field. We first introd…
Rabi and Ramsey oscillations of a Majorana qubit in a quantum dot-superconductor array
Haining Pan, Sankar Das Sarma, Chun-Xiao Liu
The Kitaev chain can be engineered within a quantum dot-superconductor array, hosting Majorana zero modes at fine-tuned sweet spots. In this work, we propose and simulate the occur…
Self-consistent theory for the fractional quantum anomalous Hall effect in rhombohedral pentalayer graphene
Ke Huang, Xiao Li, Sankar Das Sarma +1
The fractional quantum anomalous Hall (FQAH) effect in rhombohedral pentalayer graphene (PLG) has attracted significant attention due to its potential for observing exotic quantum…
