标题： Interplay of charge and vorticity quantization in superconducting Coulomb blockaded island

摘要： 库珀对的角动量或涡旋性强烈影响通过单电子晶体管中的小超导（S）岛的电荷转移。 介于微观超导体中电荷和旋转自由度之间的相互作用是通过涡旋对电子-空穴激发的量子力学谱的影响发生的。 涡旋中的亚能隙准粒子能级可以容纳一个额外的电子，从而抑制所谓的S岛中的奇偶效应。 我们建议通过由周期性磁场控制的交替涡旋进入和退出引起的电荷泵效应来测量量子化涡旋与电荷之间的相互作用。 显示英文摘要

摘要： The angular momentum or vorticity of Cooper pairs is shown to affect strongly the charge transfer through a small superconducting (S) island of a single electron transistor. This interplay of charge and rotational degrees of freedom in a mesoscopic superconductor occurs through the effect of vorticity on the quantum mechanical spectrum of electron-hole excitations. The subgap quasiparticle levels in vortices can host an additional electron, thus, suppressing the so-called parity effect in the S island. We propose to measure this interaction between the quantized vorticity and electric charge via the charge pumping effect caused by alternating vortex entry and exit controlled by a periodic magnetic field.
