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…

Cone-dependent retro and specular Andreev reflections in AA-stacked bilayer graphene
Wei-Tao Lu, Qing-Feng Sun
We theoretically study the Andreev reflection (AR) in AA-stacked bilayer graphene/superconductor (AABG/SC) junction. AABG has a linear gapless energy band with two shifted Dirac co…
