Majorana dc Josephson current mediated by a quantum dot
Luting Xu, Xin-Qi Li, Qing-Feng Sun
The Josephson supercurrent through the hybrid Majorana--quantum dot--Majorana junction is investigated. We particularly analyze the effect of spin-selective coupling between the Ma…
Two-Dimensional Lattice Model for the Surface States of Topological Insulators
Yan-Feng Zhou, Hua Jiang, X. C. Xie +1
The surface states in three-dimensional (3D) topological insulators (TIs) can be described by a two-dimensional (2D) continuous Dirac Hamiltonian. However, there exists the Fermion…
Inelastic Kondo-Andreev tunnelings in a vibrating quantum dot
Zhan Cao, Tie-Feng Fang, Qing-Feng Sun +1
Phonon-assisted electronic tunnelings through a vibrating quantum dot embedded between normal and superconducting leads are studied in the Kondo regime. In such a hybrid device, wi…
Effect of magnetic field on a magnetic topological insulator film with structural inversion asymmetry
Shu-feng Zhang, Hua Jiang, X. C. Xie +1
The effect of magnetic field on an ultrathin magnetic topological insulator film with structural inversion asymmetry is investigated. We introduce the phase diagram, calculate the…
Topological states and quantized current in helical molecules
Ai-Min Guo, Qing-Feng Sun
We report a theoretical study of electron transport along helical molecules under an external electric field, which is perpendicular to the helix axis of the molecule. Our results…
Interference Effect of Majorana Fermions in a Spin-orbit Coupled Superconducting Wire
Jie Liu, Juntao Song, Qing-Feng Sun +1
Two majorana Fermions (MFs) localized at the two ends of the topological superconducting wire can interfere with each other and form the well known Josephson current. We revea…
