AI总结：
本文研究通过耦合两个热库（其中一个温度远高于平衡临界温度）稳定BCS超导体中的非平衡稳态，实现s波和d波超导的非热配对，并讨论了腔实验中的可能实现。
AI中文摘要：
将超导稳定在其平衡态之外一直是非平衡态工程的目标之一。我们报道了耦合到两个热库的BCS超导体中存在非热配对能隙，其中一个热库的温度可以远高于平衡态$T_c$。超导态由弱耦合到打破细致平衡条件的热库所稳定的高度非平衡稳态实现。该稳态可由一个以相关Bogoliubov准粒子化学势为参数的广义吉布斯系综很好地描述。我们报道了s波和d波超导体中一种强的非微扰效应，并讨论了其在基于腔的实验中的可能实现。
英文摘要：
Stabilizing superconductivity beyond its equilibrium regime has been one of the quests of nonequilibrium state engineering. We report the presence of nonthermal pairing gap in BCS superconductors coupled to two thermal baths, where one of the baths can be at a temperature well above the equilibrium $T_c$. Superconducting state is enabled by a highly non-equilibrium steady state stabilized by weak coupling to baths that break detailed balance condition. The steady-state is well described by a generalized Gibbs ensemble parametrized with chemical potentials for associated Bogoliubov quasiparticle. A strong, non-perturbative effect is reported for both $s$-wave and $d$-wave superconductors, and its possible realization in cavity-based experiments is discussed.
