摘要:

我们提出了超导凝聚体在电磁波场中产生的光致伏特效应的理论描述。交流霍尔效应和光子牵引被证明源于超导载流子的二阶非线性响应,该响应由电子-空穴不对称性与入射电磁波产生的电荷不平衡的联合作用导致的载流子浓度抑制所引起。基于具有复弛豫常数的含时金兹堡-朗道理论,我们发展了这些现象的现象学描述,并研究了入射到超导体表面的微波辐射所感生的直流超电流和二次谐波的行为。

英文摘要:

We suggest a theoretical description of the photogalvanic phenomena arising in superconducting condensates in the field of electromagnetic wave. The ac Hall effect and photon drag are shown to originate from the second-order nonlinear response of superconducting carriers caused by the suppression of their concentration due to the combined influence of the electron - hole asymmetry and charge imbalance generated by the incident electromagnetic wave. Starting from the time-dependent Ginzburg-Landau theory with the complex relaxation constant we develop a phenomenological description of these phenomena and investigate the resulting behavior of the dc supercurrent and second harmonic induced by microwave radiation incident on a superconductor surface.
