Photomagnetic-Chiral Anisotropy mediated by Chirality-Driven Asymmetric Spin Splitting

Tianwei Ouyang, Hang Su, Wanning Zhang +4

Photomagnetic effects (PMEs), intrinsic to transition metals, arises from the interaction between light-induced angular momentum and electronic spin. These effects are suppressed i…

Identification of gapless phases by a twisting operator

Hang Su, Tengzhou Zhang, Yuan Yao +1

We propose a general necessary condition for a spin chain with SO(3) spin-rotation symmetry to be gapped. Specifically, we prove that the ground state(s) of an SO(3)-symmetric gapp…
