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…
Frustration-enhanced persistent currents in correlated trimer nanorings
Tie-Feng Fang, Wei-Tao Lu, Ai-Min Guo +1
We investigate the persistent current in a correlated trimer nanoring comprising of three magnetic atoms, which sits on a metallic host and encloses a magnetic flux. In the molecul…
Antiferromagnetic superlattices: anisotropic band and spin-valley valve in buckled two-dimensional materials
Wei-Tao Lu, Tie-Feng Fang, Qing-Feng Sun
Antiferromagnetic superlattices (AFSL) are proposed based on the buckled hexagonal two-dimensional materials, which can be realized by the proximity effect of the periodically depo…
Superconducting lens and Josephson effect in AA-stacked bilayer graphene
Wei-Tao Lu, Tie-Feng Fang, Qing-Feng Sun
We study the superconducting transport phenomena, involving lensing effect and supercurrent in AA-stacked bilayer graphene, which is characterized by a linear gapless band with two…
