Reversibility of dynamics and multiple-quantum coherences
arXiv:1412.8199 · doi:10.1103/PhysRevE.92.052903
Abstract
In spin systems, the decay of the Loschmidt echo in the time-reversal experiment (evolution, perturbation, time-reversed evolution) is linked to the generation of multiple-quantum coherences. The approach is extended to other systems, and the general problem of reversibility of quantum dynamics is analyzed.
