Equal-spin and oblique-spin crossed Andreev reflections in ferromagnet/Ising superconductor/ferromagnet junction
Wei-Tao Lu, Qing-Feng Sun, Qiang Cheng
We study the subgap transport through a ferromagnet/Ising superconductor/ferromagnet (F/ISC/F) junction by solving the Bogoliubov-de Gennes equations. It is found that the crossed…
Spin-valley polarized edge states and quantum anomalous Hall states controlled by side potential in 2D honeycomb lattices
Wei-Tao Lu, Qing-Feng Sun, Yun-Fang Li +1
Based on the tight-binding formalism, we study the effect of side potential on the spin and valley related electronic property of D honeycomb lattices with intrinsic spin-orbit…
Band bending and zero-conductance resonances controlled by edge electric fields in zigzag silicene nanoribbons
Wei-Tao Lu, Qing-Feng Sun, Hong-Yu Tian +2
We study the band structure and transport property of a zigzag silicene nanoribbon when the electric fields are applied to the edges. It is found that a band bending could be induc…
Topologically protected magnetoresistance by quantum anomalous Hall effect
Wei-Tao Lu, Qing-Feng Sun
Recently, antiferromagnetic (AF) materials have attracted rapid attention, because they are considered as outstanding candidates to replace the widely used ferromagnets in the next…
Topological phase transition driven by magnetic field in one-dimensional topological superconductor rings
Cheng-Ming Miao, Qing-Feng Sun, Ying-Tao Zhang
We study the energy spectrum and transport property of a one-dimensional Kitaev quantum ring in a threading magnetic field. It is demonstrated that the magnetic field can effective…
Spin phase regulated spin Josephson supercurrent in topological superconductor
Yue Mao, Qing-Feng Sun
Without applied bias voltage, a superconducting phase difference can drive a charge Josephson supercurrent in a superconductor junction. In analogy, we here theoretically propose a…
