Transmission phase shift of phonon-assisted tunneling through a quantum dot
Juntao Song, Qing-feng Sun, Hua Jiang +1
The influence of electron-phonon interaction on the transmission phase shift of an electron passing through a quantum dot is investigated by using the scattering theory. The transm…
Measuring the phonon-assisted spectral function by using a non-quilibrium three-terminal single-molecular device
Juntao Song, Qing-feng Sun, Jinhua Gao +1
The electron transport through a three-terminal single-molecular transistor (SMT) is theoretically studied. We find that the differential conductance of the third and weakly couple…
Quantum Blockades and Loop Currents in Graphene with Topological Defects
Yan-Yang Zhang, Jiang-Ping Hu, B. A. Bernevig +3
We investigate the effect of topological defects on the transport properties of a narrow ballistic ribbon of graphene with zigzag edges. Our results show that the longitudinal cond…
An Ideal Channel of Long Distance Entanglement in Spin Systems
Xiao-Qiang Xi, T. Zhang, R. H. Yue +2
We propose a scheme for using spin chain to realize an ideal channel of long distance entanglement. The results show that there has different entanglement in different Hilbert subs…
Designing a Spin Channel for Perfect Quantum Communication
Xiao-Qiang Xi, T. Zhang, R. H. Yue +2
We propose a scheme for using a spin chain with fixed symmetry interaction as a channel for perfect quantum communication. The perfect quantum communication is determined by the ei…
Abnormal Electronic Transport in Disordered Graphene Nanoribbon
Yan-Yang Zhang, Jiang-Ping Hu, X. C. Xie +1
We investigate the conductivity of graphene nanoribbons with zigzag edges as a function of Fermi energy in the presence of the impurities with different potential range.…
