Universal Spectral Mirage Gaps in Superconductors with Time-Reversal-Symmetric Spin-Orbit Coupling
Xusheng Wang, Gaomin Tang, Shuai-Hua Ji
Spectral mirage gaps, regarded as evidence of finite-energy pairing correlations, have so far been mainly studied in superconductors with Ising spin-orbit coupling (SOC). Here, we…
First-Order Transitions in Weak Ising Spin-Orbit-Coupled Superconductors
Xusheng Wang, Gaomin Tang, Shuai-hua Ji
Ising spin-orbit coupling (ISOC) can strongly protect superconductivity against exchange-field-induced depairing, typically leading to critical fields far exceeding the Pauli limit…
Temperature-Induced Superconductivity Enhancement under Large Exchange Field
Xusheng Wang, Lianyi He, Shuai-hua Ji
Through a comprehensive free energy analysis, we demonstrate that finite temperature can simultaneously weaken superconductivity and mitigate spin polarization induced depairing, l…
Unified Description for Reentrance and Tc Enhancement in Ferromagnetic Superconductors
Xusheng Wang, Lianyi He, Shuaihua Ji
Ferromagnetic superconductors, where ferromagnetism and superconductivity coexist despite their antagonism, exhibit strikingly diverse behaviors. Depending on the interplay between…
