摘要
By exact numerical and master equation approaches, we show that a central spin-1/2 can be configured to probe internal bath dynamics. System-bath interactions cause Rabi oscillations in the detector and periodic behavior of fidelity. This period is highly sensitive to the strength of the bath self-interactions. and can be used to calculate the intra-bath coupling. (C) 2007 Elsevier B.V. All rights reserved.
