Unconventional Spin Valve Based on Normal Metal/Chiral Molecule/Altermagnet Junctions
Tian-Yi Zhang, Peng-Yi Liu, Yu-Fei Sun +2
Chiral molecules have attracted broad interdisciplinary interest for their ability to produce highly spin-polarized current. This phenomenon, known as the chiral-induced spin selec…
Quantum anomalous Hall effect in chiral semimetals
Peng-Yi Liu, Yu-Hao Wan, Qing-Feng Sun
The quantum anomalous Hall (QAH) effect is conventionally understood to exist only in Chern insulators, while a recent study has shown that ferromagnetic metals can also host the Q…
Engineering chiral-induced spin selectivity in an artificial topological quantum well
Lizhou Liu, Peng-Yi Liu, Tian-Yi Zhang +1
Chiral-induced spin selectivity (CISS) is a striking phenomenon in which spin-unpolarized electrons become spin-polarized after traversing a chiral medium. Theoretical studies have…
The emergence of net chirality in two-dimensional Dirac fermions system with altermagnetic mass
Peng-Yi Liu, Yu-Hao Wan, Qing-Feng Sun
In two-dimensional lattice systems, massless Dirac fermions undergo doubling, leading to the cancellation of net chirality. We demonstrate that the recently discovered altermagneti…
