Elastic scattering of surface states on three-dimensional topological insulators
Jing Wang, Bang-Fen Zhu
Topological insulators as new type of quantum matter materials are characterized by a full insulating gap in the bulk and gapless edge/surface states which are protected by time-re…
Optical effects of spin currents in semiconductors
Jing Wang, Sheng-Nan Ji, Bang-Fen Zhu +1
A spin current has novel linear and second-order nonlinear optical effects due to its symmetry properties. With the symmetry analysis and the eight-band microscopic calculation we…
Second-order nonlinear optical effects of spin currents
Jing Wang, Bang-Fen Zhu, Ren-Bao Liu
A pure spin current formed by opposite spins moving in opposite directions is a rank-2 axial tensor which breaks the inversion symmetry. Thus a spin current has a second-order opti…
Coherent spin control by electromagnetic vacuum fluctuations
Jing Wang, Ren-Bao Liu, B. -F. Zhu +2
In coherent control, electromagnetic vacuum fluctuations usually cause coherence loss through irreversible spontaneous emission. However, since the dissipation via emission is esse…
Direct measurement of a pure spin current by a polarized light beam
Jing Wang, Bang-Fen Zhu, Ren-Bao Liu
The photon helicity may be mapped to a spin-1/2, whereby we put forward an intrinsic interaction between a polarized light beam as a ``photon spin current'' and a pure spin current…
