A spin dephasing mechanism mediated by the interplay between the spin-orbit coupling and the asymmetrical confining potential in semiconductor quantum dot
Rui Li
Understanding the spin dephasing mechanism is of fundamental importance in all potential applications of the spin qubit. Here we demonstrate a spin dephasing mechanism in semicondu…
Spin manipulation and spin dephasing in quantum dot integrated with a slanting magnetic field
Rui Li
A slanting magnetic field is usually used to realize a slight hybridization between the spin and orbital degrees of freedom in a semiconductor quantum dot, such that the spin is ma…
Spin-relaxation anisotropy in a nanowire quantum dot with strong spin-orbit coupling
Zhi-Hai Liu, Rui Li
We study the impacts of the magnetic field direction on the spin-manipulation and the spin-relaxation in a one-dimensional quantum dot with strong spin-orbit coupling. The energy s…
The impacts of the quantum-dot confining potential on the spin-orbit effect
Rui Li, Zhi-Hai Liu, Yidong Wu +1
For a nanowire quantum dot with the confining potential modeled by both the infinite and the finite square wells, we obtain exactly the energy spectrum and the wave functions in th…
Energy spectrum, the spin polarization, and the optical selection rules of the Kronig-Penney superlattice model with spin-orbit coupling
Rui Li
The Kronig-Penney model, an exactly solvable one-dimensional model of crystal in solid physics, shows how the allowed and forbidden bands are formed in solids. In this paper, we st…
Hyperfine interaction mediated electric-dipole spin resonance: the role of frequency modulation
Rui Li
The electron spin in a semiconductor quantum dot can be coherently controlled by an external electric field, an effect called electric-dipole spin resonance (EDSR). Several mechani…
Anisotropic exchange coupling in a nanowire double quantum dot with strong spin-orbit coupling
Rui Li, J. Q. You
A spin-orbit qubit is a hybrid qubit that contains both orbital and spin degrees of freedom of an electron in a quantum dot. Here we study the exchange coupling between two spin-or…
Controlling a Nanowire Spin-Orbit Qubit via Electric-Dipole Spin Resonance
Rui Li, J. Q. You, C. P. Sun +1
A semiconductor nanowire quantum dot with strong spin-orbit coupling (SOC) can be used to achieve a spin-orbit qubit. In contrast to a spin qubit, the spin-orbit qubit can respond…
