Non-Markovian Transmission through Two Quantum Dots Connected by a Continuum
Yunshan Cao, Luting Xu, Jianyu Meng +1
We consider a transport setup containing a double-dot connected by a continuum. Via an exact solution of the time-dependent Schrödinger equation, we demonstrate a highly non-Markov…
Angular momentum transfer torques in spin valves with perpendicular magnetization
Xingtao Jia, Ying Li, Ke Xia +1
Spin valves incorporating perpendicularly magnetized materials are promising structures for memory elements and high-frequency generators. We report the angular dependence of the s…
Magnetic Core-Shell Structure and Proximity Effect in 7 nm Single-Crystal Co3O4 Nanowires
Ping Lv, Yan Zhang, Rui Xu +2
We present a study of magnetic properties of single-crystal Co3O4 nanowires with diameter about 7 nm. The nanowires expose (111) planes composed of plenty of Co3+ cations and exhib…
Decoherence and the retrieval of lost information
Yin Ye, Yunshan Cao, Xin-Qi Li +1
We found that in contrast with the common premise, a measurement on the environment of an open quantum system can {\em reduce} its decoherence rate. We demonstrate it by studying a…
Influence of the Surface Structure and Vibration Mode on the Resistivity of Cu Films
Ya-Ni Zhao, Shi-Xian Qu, Ke Xia
The influence of the surface structure and vibration mode on the resistivity of Cu films and the corresponding size effect are investigated. The temperature dependent conductivitie…
Large-deviation analysis for counting statistics in mesoscopic transports
Jun Li, Yu Liu, Jing Ping +3
We present an efficient approach, based on a number-conditioned master equation, for large-deviation analysis in mesoscopic transports. Beyond the conventional full-counting-statis…
