Quantum Zeno and Anti-Zeno Effect without Rotating Wave Approximation
H. Zheng, S. Y. Zhu
The effect of the anti-rotating terms on the short-time evolution and the quantum Zeno (QZE) and anti-Zeno (AQZE) effects is studied for a two-level system coupled to a bosonic env…
Evidence for the intrinsic ferromagnetism of semiconductor (Ga,Cr)As revealed by magnetic circular dichroism
H. D. Gan, H. Z. Zheng, J. F. Bi +6
To clarify whether or not (Ga,Cr)As is an intrinsic diluted magnetic semiconductor, a systematic study of the magnetic circular dichroism (MCD) was carried out for a series of (Ga,…
Electrical Control of Dynamic Spin Splitting Induced by Exchange Interaction as Revealed by Time Resolved Kerr Rotation in a Degenerate Spin-Polarized Electron Gas
F. Zhang, H. Z. Zheng, Y. Ji +2
The manipulation of spin degree of freedom have been demonstrated in spin polarized electron plasma in a heterostructure by using exchange-interaction induced dynamic spin splittin…
Quantum dynamics of a qubit coupled with structured bath
Peihao Huang, H. Zheng
The dynamics of an unbiased spin-boson model with Lorentzian spectral density is investigated theoretically in terms of the perturbation theory based on a unitary transformation. T…
Interplay between s-d exchange interaction and Rashba effect: spin-polarized transport
W. Yang, Kai Chang, X. G. Wu +2
We investigate the spin-polarized transport properties of a two-dimensional electron gas in a n-type diluted magnetic narrow gap semiconductor quantum well subjected to a perpendic…
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…
