Spin states in InAs/AlSb/GaSb semiconductor quantum wells
Jun Li, Wen Yang, Kai Chang
We investigate theoretically the spin states in InAs/AlSb/GaSb broken-gap quantum wells by solving the Kane model and the Poisson equation self-consistently. The spin states in InA…

Universality of Uhrig dynamical decoupling for suppressing qubit pure dephasing and relaxation
Wen Yang, Ren-Bao Liu
The optimal -pulse dynamical decoupling discovered by Uhrig for a spin-boson mmodel [Phys. Rev. Lett, {\bf 98}, 100504 (2007)] is proved to be universal in suppressing to $O(T^{…

Quantum many-body theory of qubit decoherence in a finite-size spin bath
Wen Yang, Ren-bao Liu
Decoherence of a center spin or qubit in a spin bath is essentially determined by the many-body bath evolution. We develop a cluster-correlation expansion (CCE) theory for the spin…
