保持热失衡超导线材局部温度低于临界值

Maintaining the local temperature below the critical value in thermally out of equilibrium superconducting wires

Yonatan Dubi, Massimiliano Di Ventra

摘要:

本文用开放量子系统的广义理论结合平均场论研究了与不同温度热浴接触的超导导线。结果表明,根据较冷的浴的温度,较热的浴的温度可以大大超过平衡临界温度,并且仍然在导线中的局部温度保持低于临界温度,因此导线保持在超导状态。研究了接触面积和无序度的影响。最后,一个实验装置,建议来测试我们的预测。

英文摘要:

A generalized theory of open quantum systems combined with mean-field theory is used to study a superconducting wire in contact with thermal baths at different temperatures. It is shown that, depending on the temperature of the colder bath, the temperature of the hotter bath can greatly exceed the equilibrium critical temperature, and still the local temperature in the wire is maintained below the critical temperature and hence the wire remains in the superconducting state. The effects of contact areas and disorder are studied. Finally, an experimental setup is suggested to test our predictions.
