Josephson effects in the spin-triplet superconductor/altermagnet/spin-triplet superconductor junctions: the detection of the intrinsic -vector
Ya-Ting Han, Li-Juan Chen, Wen-Ting Liu +2
We study the Josephson effects in the spin-triplet superconductor/altermagnet/spin-triplet superconductor junctions using the Green's function method. It is found that the current-…
Helimagnetic Josephson diode effect
Qiang Cheng, Yu-Chen Zhuang, Qing-Feng Sun
We study the Josephson diode effect in the one-dimensional superconductor/helimagnet/superconductor junctions using the Green's function method. For the spin-singlet -wave pairi…
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…
Controllable Josephson diode effect, - transition and switch effect in the superconductor/two-dimensional Weyl nodal line semimetal/superconductor junctions
Wen-Ting Liu, Shu-Chang Zhao, Qiang Cheng +1
We study the Josephson effects in the superconductor/two-dimensional Weyl nodal line semimetal/superconductor junctions using the Green's function method. When the Rashba spin-orbi…
Field-free Josephson diode effect in altermagnet/normal metal/altermagnet junctions
Qiang Cheng, Yue Mao, Qing-Feng Sun
The field-free and highly efficient diodes with the nonreciprocity of supercurrent are believed to be the core block of the superconducting computing devices without dissipation. I…

Qiang Cheng, Qing-Feng Sun
We study the Josephson effect in the spin-singlet superconductor/altermagnet/spin-triplet superconductor junctions using the Green's function method. The current-phase difference r…
Perfect crossed Andreev reflection in the proximitized graphene/superconductor/proximitized graphene junctions
Shu-Chang Zhao, Lu Gao, Qiang Cheng +1
We study the crossed Andreev reflection and the nonlocal transport in the proximitized graphene/supercondcutor/proximitized graphene junctions with the pseudospin staggered potenti…
Spin-valley dependent double Andreev reflections in the proximitized graphene/superconductor junction
Lu Gao, Qiang Cheng, Qing-Feng Sun
We study the Andreev reflections and the quantum transport in the proximitized graphene/superconductor junction. The proximitized graphene possesses the pseudospin staggered potent…
Continuously Tunable Berry Phase and Valley-Polarized Energy Spectra in Bilayer Graphene Quantum Dots
Ya-Ning Ren, Qiang Cheng, Qing-Feng Sun +1
Berry phase plays an important role in determining many physical properties of quantum systems. However, a Berry phase altering energy spectrum of a quantum system is comparatively…
Specular Andreev reflection and its detection
Qiang Cheng, Qing-Feng Sun
We propose a universal method to detect the specular Andreev reflection taking the simple two dimensional Weyl nodal-line semimetal-superconductor double-junction structure as an e…
Spatial and Magnetic Confinement of Massless Dirac Fermions
Ya-Ning Ren, Qiang Cheng, Chao Yan +4
The massless Dirac fermions and the ease to introduce spatial and magnetic confinement in graphene provide us unprecedented opportunity to explore confined relativistic matter in t…
