Analytical result on the supercurrent through a superconductor/quantum-dot/superconductor junction
Wei Li, Yu Zhu, Tsung-han Lin
We present an analytical result for the supercurrent across a superconductor/quantum-dot/superconductor junction. By converting the current integration into a special contour integ…
Probing Spin States of Coupled Quantum Dots by dc Josephson Current
Yu Zhu, Qing-feng Sun, Tsung-han Lin
We propose an idea for probing spin states of two coupled quantum dots (CQD), by the dc Josephson current flowing through them. This theory requires weak coupling between CQD and e…
Excess Kondo resonance in a quantum dot device with normal and superconducting leads: the physics of Andreev-normal co-tunneling
Qing-feng Sun, Hong Guo, Tsung-han Lin
We report on a novel Kondo phenomenon of interacting quantum dots coupled asymmetrically to a normal and a superconducting lead. The effects of intradot Coulomb interaction and And…
Extraordinary Temperature Dependence of the Resonant Andreev Reflection
Yu Zhu, Qing-feng Sun, Tsung-han Lin
An extraordinary temperature dependence of the resonant Andreev reflection via discrete energy level in a normal-metal / quantum-dot / superconductor (N-QD-S) system is predicted t…
Andreev reflection through a quantum dot coupled with two ferromagnets and a superconductor
Yu Zhu, Qing-feng Sun, Tsung-han Lin
We study the Andreev reflection (AR) in a three terminal mesoscopic hybrid system, in which two ferromagnets (F and F) are coupled to a superconductor (S) through a quantum…
Asymmetric double quantum dots as a subminiature mesoscopic cell
Qing-feng Sun, Jian Wang, Tsung-han Lin
A subminiature mesoscopic cell, consisting of an asymmetric double quantum dot capacitively coupled to a nearby mesoscopic circuit, is proposed, which can transform disordered nois…
