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…
Spin polarized current in a junction of zigzag carbon nanotube
Zhan-Feng Jiang, Jian Li, Shun-Qing Shen +1
We investigated spin-resolved electronic transport through a junction composed of a nonmagnetic metal electrode and a zigzag carbon nanotube by means of self-consistent Green's fun…
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…
Casimir Forces in Trapped Dilute Bose Gas Between Two Slabs
Xiao-Lu Yu, Ran Qi, Z. B. Li +1
We discuss a Casimir force due to zero-temperature quantum fluctuations in a weakly interacting Bose-Einstein condensate (BEC) with a strong harmonic trap. The results show that th…
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.…
Controllable Josephson-Like Tunneling in Two-Component Bose-Einstein Condensates Coupled with Microwave via Feshbach Resonance and Trapping Potential
Bo Xiong, Weiping Zhang, W. M. Liu
We put forward a scheme for controlling Josephson-like tunneling in two-component Bose-Einstein condensates coupled with microwave field via Feshbach resonance and tuning aspect ra…
Topological Force and Torque in Spin-Orbit Coupling System
F. J. Huang, R. Qi, Y. D. Li +1
The topological force and torque are investigated in the systems with spin-orbit coupling. Our results show that the topological force and torque appears as a pure relativistic qua…
