A Simple Solvable Model for Heavy Fermion Superconductivity from the Two-Fluid Normal State
Jiangfan Wang, Yu Li, Yi-feng Yang
We propose an exactly solvable momentum-space Kondo-BCS model to study heavy fermion superconductivity. The Kondo interaction is local in momentum space, which can be derived from…
Effects of spin orbit coupling on proximity induced superconductivity
Vivek Mishra, Yu Li, Fu-Chun Zhang +1
We investigate the effect of spin orbit coupling on proximity induced superconductivity in a normal metal attached to a superconductor. Specifically, we consider a heterostructure…
Two-stage superconductivity in the Hatsugai-Kohmoto-BCS model
Yu Li, Vivek Mishra, Yi Zhou +1
Superconductivity in strongly correlated electrons can emerge out from a normal state that is beyond the Landau's Fermi liquid paradigm, often dubbed as "non-Fermi liquid". While t…
Enhanced two-component superconductivity in CoSi2/TiSi2 heterojunctions
Shao-Pin Chiu, Vivek Mishra, Yu Li +3
We report enhanced two-component superconductivity in (CoSi2/Si)/TiSi2 superconductor/normal-metal (S/N) heterojunctions. An enhanced superconducting transition temperature about t…
Multipole-fluctuation pairing mechanism of superconductivity in SrRuO
Yutao Sheng, Yu Li, Yi-feng Yang
Despite of many experimental and theoretical efforts, the pairing symmetry of superconductivity in SrRuO remains undecided. The accidentally degenerate is…
Effects of spin orbit coupling in superconducting proximity devices -- application to heterostructures
Vivek Mishra, Yu Li, Fu-Chun Zhang +1
Motivated by the recent findings of unconventional superconductivity in heterostructures, we study the effect of interface induced Rashba spin orbit coup…
Nearly-degenerate and pairing symmetry in the heavy fermion superconductor YbRhSi
Yu Li, Qianqian Wang, Yuanji Xu +2
Recent discovery of superconductivity in YbRhSi has raised particular interest in its pairing mechanism and gap symmetry. Here we propose a phenomenological theory of its s…
Possible nodeless -wave superconductivity in twisted bilayer graphene
Zhe Liu, Yu Li, Yi-feng Yang
Recent discovery of superconductivity in the twisted bilayer graphene has stimulated numerous theoretical proposals concerning its exact gap symmetry. Among them, or -…
Gap symmetry of the heavy fermion superconductor CeCuSi at ambient pressure
Yu Li, Min Liu, Zhaoming Fu +3
Recent observations of two nodeless gaps in superconducting CeCuSi have raised intensive debates on its exact gap symmetry, while a satisfactory theoretical basis is still…
