Hybridization and spin decoherence in heavy-hole quantum dots
Hybridization spin decoherence heavy-hole quantum dots
2010/10/27
We theoretically investigate the spin dynamics of a heavy hole con ned to a III-V semiconductor quantum dot interacting with a narrowed nuclear-spin bath. We show that band hybridization leads to an e...
A general and solvable random matrix model for spin decoherence
general and solvable random matrix model spin decoherence
2010/10/21
We propose and solve a simple but very general quantum model of an SU(2)spin interacting with a large external system with N states. The coupling is described by a random hamiltonian in a new general ...
