Geometric Correlations and Breakdown of Mesoscopic Universality in Spin Transport
I. Adagideli, Ph. Jacquod, M. Scheid +3
We construct a unified semiclassical theory of charge and spin transport in chaotic ballistic and disordered diffusive mesoscopic systems with spin-orbit interaction. Neglecting dy…
Free-induction decay and envelope modulations in a narrowed nuclear spin bath
W. A. Coish, Jan Fischer, Daniel Loss
We evaluate free-induction decay for the transverse components of a localized electron spin coupled to a bath of nuclear spins via the Fermi contact hyperfine interaction. Our pert…
Dicke model: entanglement as a finite size effect
O. Tsyplyatyev, D. Loss
We analyze Dicke model at zero temperature by matrix diagonalization to determine the entanglement in the ground state. In the infinite system limit the mean field approximation pr…
Universal phase shift and non-exponential decay of driven single-spin oscillations
F. H. L. Koppens, D. Klauser, W. A. Coish +4
We study, both theoretically and experimentally, driven Rabi oscillations of a single electron spin coupled to a nuclear spin bath. Due to the long correlation time of the bath, tw…
Measurement, control, and decay of quantum-dot spins
W. A. Coish, Vitaly N. Golovach, J. Carlos Egues +1
In this review we discuss a recent proposal to perform partial Bell-state (parity) measurements on two-electron spin states for electrons confined to quantum dots. The realization…
Rigorous Born Approximation and beyond for the Spin-Boson Model
D. P. DiVincenzo, D. Loss
Within the lowest-order Born approximation, we present an exact calculation of the time dynamics of the spin-boson model in the ohmic regime. We observe non-Markovian effects at ze…
