Exponential decay in a spin bath
W. A. Coish, Jan Fischer, Daniel Loss
We show that the coherence of an electron spin interacting with a bath of nuclear spins can exhibit a well-defined purely exponential decay for special (`narrowed') bath initial co…
Electron and hole spin dynamics and decoherence in quantum dots
D. Klauser, D. V. Bulaev, W. A. Coish +1
In this article we review our work on the dynamics and decoherence of electron and hole spins in single and double quantum dots. The first part, on electron spins, focuses on decoh…
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…
