Spintronics with a Weyl point in superconducting nanostructures
Yuguang Chen, Yuli Nazarov
We investigate transport in a superconducting nanostructure housing a Weyl point in the spectrum of Andreev bound states. A minimum magnet state is realized in the vicinity of the…
Topological properties of multi-terminal superconducting nanostructures: effect of a continuous spectrum
Evgeny Repin, Yuguang Chen, Yuli V. Nazarov
Recently, it has been shown that multi-terminal superconducting nanostructures may possess topological properties that involve Berry curvatures in the parametric space of the super…
Spin-polarized current separator based on a fork-shaped Rashba nanostructure
Xianbo Xiao, Yuguang Chen
A scheme for a spin-polarized current separator is proposed by studying the spin-dependent electron transport of a fork-shaped nanostructure with Rashba spin-orbit coupling (SOC),…
Spin polarization direction switch based on an asymmetrical quantum wire
Zhonghui Xu, Xianbo Xiao, Yuguang Chen
A scheme for a spin polarization direction switch is investigated by studying the spin-dependent electron transport of an asymmetrical quantum wire (QW) with Rashba spin-orbit coup…
Spin polarization control by electric means: proposal for a spin diode
Xianbo Xiao, Yuguang Chen
A scheme of spin diode is proposed that uses a step-like quantum wire with Rashba spin-orbit interaction, connected to two leads with different width. It is shown that a very large…
Spin Filtering in a Nonuniform Quantum Wire with Rashba Spin-Orbit Interaction
Xianbo Xiao, Xiaomao Li, Yuguang Chen
We investigate theoretically the spin-polarized electron transport for a wide-narrow-wide (WNW) quantum wire under the modulation of Rashba spin-orbit interaction (SOI). The influe…
Phase diagram of a Bose-Fermi mixture in a one-dimensional optical lattice in terms of fidelity and entanglement
Wen-Qiang Ning, Shi-Jian Gu, Chang-Qin Wu +1
We study the ground-state phase diagram of a Bose-Fermi mixture loaded in a one-dimensional optical lattice by computing the ground-state fidelity and quantum entanglement. We find…
