Identify the topological superconducting order in a multi-band quantum wire
Pei Wang, Jie Liu, Qing-feng Sun +1
How to distinguish the zero-bias peak (ZBP) caused by the Majorana fermions from that by the other effects remains a challenge in detecting the topological order of a quantum wire.…
Orbital Kondo effect in a parallel double quantum dot
Zhi-qiang Bao, Ai-Min Guo, Qing-feng Sun
We construct a theoretical model to study the orbital Kondo effect in a parallel double quantum dot (DQD). Recently, pseudospin-resolved transport spectroscopy of the orbital Kondo…
Revisit the spin-FET: Multiple reflections, inelastic scattering, and lateral size effects
Luting Xu, Xin-Qi Li, Qing-feng Sun
We revisit the spin-injected field effect transistor (spin-FET) by simulating a lattice model based on recursive lattice Green's function approach. In the one-dimensional case and…
Delocalization and scaling properties of low-dimensional quasiperiodic systems
Ai-Min Guo, X. C. Xie, Qing-feng Sun
In this paper, we explore the localization transition and the scaling properties of both quasi-one-dimensional and two-dimensional quasiperiodic systems, which are constituted from…
Enhanced spin-polarized transport through DNA double helix by gate voltage
Ai-Min Guo, Qing-feng Sun
We report on a way to manipulate the spin transport through double-stranded DNA contacted by normal-metal electrodes. On the basis of an effective model Hamiltonian, the conductanc…
Theory for electric dipole superconductivity with an application for bilayer excitons
Qing-Dong Jiang, Zhi-qiang Bao, Qing-Feng Sun +1
Exciton superfluid is a macroscopic quantum phenomenon in which large quantities of excitons undergo the Bose-Einstein condensation. Recently, exciton superfluid has been widely st…
