Shift spin photocurrents in two-dimensional systems
Hsiu-Chuan Hsu, Tsung-Wei Chen
The generation of nonlinear spin photocurrents by circularly polarized light in two-dimensional systems is theoretically investigated by calculating the shift spin conductivities.…
The semiclassical theory for spin dynamics in a disordered system
Tsung-Wei Chen, Hsiu-Chuan Hsu
We investigate the Drude model of spin dynamics in two-dimensional spin-orbit coupled systems. In the absence of an applied electric field, the spin aligns with the k-dependent eff…
Topological Anderson insulating phases in the long-range Su-Schrieffer-Heeger model
Hsu-Chuan Hsu, Tsung-Wei Chen
In the long-range Su-Schriffer-Heeger (SSH) model, in which the next nearest-neighbor hopping is considered, there exhibits a rich topological phase diagram that contains winding n…
Dynamical precession of spin in the two-dimensional spin-orbit coupled systems
Tsung-Wei Chen, Zhi-Yang Huang, Dah-Wei Chiou
We investigate the spin dynamics in the two-dimensional spin-orbit coupled system subject to an in-plane (- plane) constant electric field, which is assumed to be turned on a…
Topological phase transitions in an inverted InAs/GaSb quantum well driven by tilted magnetic fields
Hsiu-Chuan Hsu, Min-Jyun Jhang, Tsung-Wei Chen +1
The helical edge states in a quantum spin Hall insulator are presumably protected by time- reversal symmetry. However, even in the presence of magnetic field which breaks time-reve…
Out-of-plane spin polarization of edge currents in Chern insulator with Rashba spin-orbit interaction
Tsung-Wei Chen, Chin-Lun Hsiao, Chong-Der Hu
We investigate the change in the non-zero Chern number and out-of-plane spin polarization of the edge currents in a honeycomb lattice with the Haldane-Rashba interaction. This inte…
