论文摘要
我们建议动态控制约瑟夫森连接的电导率，该连接由两个弱耦合的超电原子的一个尺寸冷凝物组成。电流是由冷凝水之间的定期调制电势差引起的，从而访问了连接的电导率。通过使用隧道能量的参数驱动，我们证明了连接点的低频电导率可以增强或抑制，具体取决于驾驶频率的选择。该提案的实验实现提供了高温超导体泵送实验中光学增强的超导性的量子模拟。
We propose to dynamically control the conductivity of a Josephson junction composed of two weakly coupled one dimensional condensates of ultracold atoms. A current is induced by a periodically modulated potential difference between the condensates, giving access to the conductivity of the junction. By using parametric driving of the tunneling energy, we demonstrate that the low-frequency conductivity of the junction can be enhanced or suppressed, depending on the choice of the driving frequency. The experimental realization of this proposal provides a quantum simulation of optically enhanced superconductivity in pump-probe experiments of high temperature superconductors.
