摘要:

在时间相关的金-朗道理论的框架内,我们表明,圆偏振太赫兹或远红外辐射诱导的直流超电流,影响的动态涡旋-反涡旋对形成在介观超导体经历快速热淬火。超电流产生的洛伦兹力促进了涡旋-反涡旋分离,并允许由光的螺旋度定义的涡旋极性存活。基于这个想法,我们提出了一个两阶段的照射计划,提供了一个强大的方法控制全光产生的Abrikosov涡。

英文摘要:

Within the framework of the time-dependent Ginzburg-Landau theory we show that circularly polarized THz or far-infrared radiation induces a dc supercurrent that influences the dynamics of vortex-antivortex pair formation in a mesoscopic superconductor undergoing rapid thermal quenching. The Lorentz force arising from the supercurrents promotes vortex-antivortex separation and allows survival of the vortex polarity defined by the helicity of light. Based on this idea, we propose a two-stage irradiation scheme that provides a powerful method for controlled all-optical generation of Abrikosov vortices.
