摘要翻译:
涡旋晶格与非对称人工缺陷晶格之间的竞争在超导薄膜棘轮实验中起着至关重要的作用。我们提出了一种基于涡旋晶格重构的电流反转的新的集体机制。与以往的涡旋流反转模型不同,该机制是基于涡旋晶格对外力的全局响应。

英文摘要:
Competition between the vortex lattice and a lattice of asymmetric artificial defects is shown to play a crucial role in ratchet experiments in superconducting films. We present a novel and collective mechanism for current reversal based on a reconfiguration of the vortex lattice. In contrast to previous models of vortex current reversal, the mechanism is based on the global response of the vortex lattice to external forces.
