Spin-polarized transport in a lateral two-dimensional diluted magnetic semiconductor electron gas
W. Yang, Kai Chang, X. G. Wu +1
The transport property of a lateral two-dimensional diluted magnetic semiconductor electron gas under a spatially periodic magnetic field is investigated theoretically. We find tha…
Thermal entanglement in a two-qubit Heisenberg XXZ spin chain under an inhomogeneous magnetic field
Guo-Feng Zhang
The thermal entanglement in a two-qubit Heisenberg \emph{XXZ} spin chain is investigated under an inhomogeneous magnetic field \emph{b}. We show that the ground-state entanglement…
Spin relaxation in diluted magnetic semiconductor quantum dots
W. Yang, K. Chang
Electron spin relaxation induced by phonon-mediated s-d exchange interaction in a II-VI diluted magnetic semiconductor quantum dot is investigated theoretically. The electron-acous…
Correlation effects for semiconducting single wall carbon nanotube: a density matrix renormalization group study
Fei Ye, Bing-Shen Wang, JiZhong Lou +1
In this paper, we report the applicability of the density matrix renormalization group(DMRG) approach to the cylindrical single wall carbon nanotube (SWCN) for purpose of its corre…
