Fully Tunable Fano Resonances in Chiral Electronic Transport
Ai-Ying Ye, Zhao Yang Zeng
Fano resonance is believed to arise when a direct path interferes with a resonant path. We demonstrate that this is not true for chiral electronic transmission without additional d…
Vortex-state-mediated Josephson effect
Zhao Yang Zeng, Chong Zhang
The Josephson effect is a kind of macroscopic quantum phenomenon that supercurrent flows through a Josephson junction without any voltage applied. We predict a novel vortex-state-m…
Interference in transport through double barriers in interacting quantum wires
Shaoqing Wang, Liling Zhou, Zhao Yang Zeng
We investigate interference effects of the backscattering current through a double-barrier structure in an interacting quantum wire attached to noninteracting leads. Depending on t…
Conductance oscillation and quantization in monoatomic Al wires
Ying Xu, Xingqiang Shi, Zhi Zeng +2
We present first-principles calculations for the transport properties of monoatomic Al wires sandwiched between Al(100) electrodes. The conductance of the monoatomic Al wires oscil…
Current rectification by asymmetric molecules: An ab initio study
Yan-hong Zhou, Xiao-hong Zheng, Ying Xu +1
We study current rectification effect in an asymmetric molecule HOOC-CH-(CH) sandwiched between two Aluminum electrodes using an {\sl ab initio} nonequilibrium Gree…
Pumping Current in a Quantum Dot by an Oscillating Magnetic Field
Zhao Yang Zeng, Hong Li, Baowen Li
We investigate spin and charge current through a quantum dot pumped by a time-varying magnetic field. Using the density matrix method, quantum rate equations for the electronic occ…
