超导诱导宏观共振隧穿

Superconductivity-induced macroscopic resonant tunneling

M. C. Goorden, Ph. Jacquod, J. Weiss

摘要:

我们分析和数值模拟表明,通过$π$偏置混沌约瑟夫森结的电导增强了几个数量级的短波长制度。我们确定这种效果背后的机制为{ \it宏观共振隧穿}通过一个宏观数量的低能量准简并Andreev水平。

英文摘要:

We show analytically and by numerical simulations that the conductance through $π$-biased chaotic Josephson junctions is enhanced by several orders of magnitude in the short-wavelength regime. We identify the mechanism behind this effect as {\it macroscopic resonant tunneling} through a macroscopic number of low-energy quasi-degenerate Andreev levels.
