超导体中超电流的弹道加速

The ballistic acceleration of a supercurrent in a superconductor

Gabriel F. Saracila, Milind N. Kunchur

摘要:

超导体最原始但最难以捉摸的电流-电压(I-V)响应之一是在第一次施加电压后其超电流稳定增长。目前的工作采用了一个测量系统,可以同时跟踪和关联I(t)和V(t)与亚纳秒的定时精度,导致在第一个明确的时域测量的瞬态阶段,其中量子系统显示牛顿样的响应。该技术打开了大门,在凝聚态系统中的其他时间相关的传输现象的控制调查。

英文摘要:

One of the most primitive but elusive current-voltage (I-V) responses of a superconductor is when its supercurrent grows steadily after a voltage is first applied. The present work employed a measurement system that could simultaneously track and correlate I(t) and V(t) with sub-nanosecond timing accuracy, resulting in the first clear time-domain measurement of this transient phase where the quantum system displays a Newtonian like response. The technique opens doors for the controlled investigation of other time dependent transport phenomena in condensed-matter systems.
