Algebraic Criterion and Graph-Theoretic Construction of Intrinsic Superconducting Diode Effects
Ran Wang, Ning Hao
The intrinsic superconducting diode effect (SDE) is distinguished from the Josephson diode effect (JDE) by its manifestation of nonreciprocal critical current phenomena within a mo…
Spin-Orbital Intertwined Topological Superconductivity in a Class of Correlated Noncentrosymmetric Materials
Lichuan Wang, Ran Wang, Xinliang Huang +2
In this study, we propose an alternative route to achieving topological superconductivity (TSC). Our approach applies to a new class of correlated noncentrosymmetric materials that…
Finite-Momentum Pairing State in Unconventional Rashba Systems
Ran Wang, Song-Bo Zhang, Ning Hao
In systems with unconventional Rashba bands, we propose that a finite-momentum pairing state can emerge without the need for an external magnetic field. We analyze the phase transi…
Superconductivity in Two-Dimensional Systems with Unconventional Rashba Bands
Ran Wang, Jiayang Li, Xinliang Huang +3
In two-dimensional system with Rashba spin-orbit coupling, it is well-known that superconductivity can have mixed spin-singlet and -triplet parity, and the -vector…
