Fractional Spin Hall Effect in Atomic Bose Gases
Xiong-Jun Liu, Xin Liu, L. C. Kwek +1
We propose fractional spin hall effect (FSHE) by coupling pseudospin states of cold bosonic atoms to optical fields. The present scheme is an extension to interacting bosonic syste…

Spin Hall Effect in Atoms
Xiong-Jun Liu, Xin Liu, L. C. Kwek +1
We propose an optical means to realize a spin hall effect (SHE) in neutral atomic system by coupling the internal spin states of atoms to radiation. The interaction between the ext…

Quantum Spin Current Induced Through Optical Fields
Xiong-Jun Liu, Xin Liu, L. C. Kwek +2
We propose a scheme to generate quantum spin current via optical dipole transition process. By coupling a three-level system based on the spin states of charged particles (electron…
