约瑟夫森结中超导岛的振动

Vibrating Superconducting Island in a Josephson Junction

J. Fransson, J. -X. Zhu, A. V. Balatsky

摘要:

我们考虑了一种纳米机械-超导相结合的器件,它允许库珀对隧穿干扰中间超导岛的机械运动。两个超导体之间的超导岛的机械振荡的耦合导致电子隧穿产生超导电流,该超导电流由岛的振荡运动调制。这种耦合产生交替的有限和消失的超导相的功能。电流峰值对超导体之间的相对相移很敏感。该装置可用于研究超导电子学中的纳机电耦合。

英文摘要:

We consider a combined nanomechanical-supercondcuting device that allows the Cooper pair tunneling to interfere with the mechanical motion of the middle superconducting island. Coupling of mechanical oscillations of a superconducting island between two superconducting leads to the electronic tunneling generate a supercurrent which is modulated by the oscillatory motion of the island. This coupling produces alternating finite and vanishing supercurrent as function of the superconducting phases. Current peaks are sensitive to the superconducting phase shifts relative to each other. The proposed device may be used to study the nanoelectromechanical coupling in case of superconducting electronics.
