论文摘要
我们研究了在有吸引力的相互作用的情况下，研究耗散性浮部电子系统中的内在超导性。基于均值场外处理以外的功能性Keldys理论，我们发现该系统显示了时间周期性的骨凝结，并达到了固有的耗散浮力超导（SC）阶段。由于耗散和周期性调制之间的相互作用，Floquet SC间隙变为“软”，并包含具有有限寿命的扩散的费米子模式。然而，即使在存在耗散的情况下，剂量凝结的骨气模式仍在传播。
We study the intrinsic superconductivity in a dissipative Floquet electronic system in the presence of attractive interactions. Based on the functional Keldysh theory beyond the mean-field treatment, we find that the system shows a time-periodic bosonic condensation and reaches an intrinsic dissipative Floquet superconducting (SC) phase. Due to the interplay between dissipations and periodic modulations, the Floquet SC gap becomes "soft" and contains the diffusive fermionic modes with finite lifetimes. However, bosonic modes of the bosonic condensation are still propagating even in the presence of dissipations.
