强耦合下的受激超导

Stimulated superconductivity at strong coupling

Ning Bao, Xi Dong, Eva Silverstein, Gonzalo Torroba

摘要:

用随时间变化的源刺激系统可以增强不稳定性,从而增加系统转变为感兴趣的低温相(例如超导性或超流性)的临界温度。在回顾了非平衡BCS理论(及其边缘费米液体推广)中的这一现象后,我们分析了全息超导体中的效应。我们表现出一个简单的制度,其中的转变温度增加参数,因为我们增加的频率的时间依赖源。

英文摘要:

Stimulating a system with time dependent sources can enhance instabilities, thus increasing the critical temperature at which the system transitions to interesting low-temperature phases such as superconductivity or superfluidity. After reviewing this phenomenon in non-equilibrium BCS theory (and its marginal fermi liquid generalization) we analyze the effect in holographic superconductors. We exhibit a simple regime in which the transition temperature increases parametrically as we increase the frequency of the time-dependent source.
