Nonequilibrium spin transport on Au(111) surfaces
Ming-Hao Liu, Son-Hsien Chen, Ching-Ray Chang
The well-known experimentally observed \textit{sp}-derived Au(111) Shockley surface states with Rashba spin splitting are perfectly fit by an effective tight-binding model, conside…
Current-induced spin polarization in spin-orbit-coupled two-dimensional electron systems
Ming-Hao Liu, Son-Hsien Chen, Ching-Ray Chang
Current-induced spin polarization (CISP) is rederived in ballistic spin-orbit-coupled electron systems, based on equilibrium statistical mechanics. A simple and useful picture is c…
Non-Abelian spin-orbit gauge: Persistent spin helix and quantum square ring
Son-Hsien Chen, Ching-Ray Chang
We re-express the Rashba and Dresselhaus interactions as non-Abelian spin-orbit gauges and provide a new perspective in understanding the persistent spin helix [Phys. Rev. Lett. 97…
Broken spin-Hall accumulation symmetry by magnetic field and coexisted Rashba and Dresselhaus interactions
Son-Hsien Chen, Ming-Hao Liu, Kuo-Wei Chen +1
The spin-Hall effect in the two-dimensional electron gas (2DEG) generates symmetric out-of-plane spin Sz accumulation about the current axis in the absence of external magnetic fie…
Local spin density in two-dimensional electron gas with hexagonal boundary
Son-Hsien Chen, Ming-Hao Liu, Ching-Ray Chang
The intrinsic spin-Hall effect in hexagon-shaped samples is investigated. To take into account the spin-orbit couplings and to fit the hexagon edges, we derive the triangular versi…
Precessionless spin transport wire confined in quasi-two-dimensional electron systems
Ming-Hao Liu, Son-Hsien Chen, Ching-Ray Chang
We demonstrate that in an inversion-asymmetric two-dimensional electron system 2DES with both Rashba and Dresselhaus spin-orbit couplings taken into account, certain transport dire…
