Signatures of a quantum dynamical phase transition in a three-spin system in presence of a spin environment
Gonzalo A. Alvarez, Patricia R. Levstein, Horacio M. Pastawski
We have observed an environmentally induced quantum dynamical phase transition in the dynamics of a two spin experimental swapping gate [J. Chem. Phys. 124, 194507 (2006)]. There,…
Time Reversal Mirror and Perfect Inverse Filter in a Microscopic Model for Sound Propagation
Hernan L. Calvo, Ernesto P. Danieli, Horacio M. Pastawski
Time reversal of quantum dynamics can be achieved by a global change of the Hamiltonian sign (a hasty Loschmidt daemon), as in the Loschmidt Echo experiments in NMR, or by a local…
Decoherence under many-body system-environment interactions: a stroboscopic representation based on a fictitiously homogenized interaction rate
Gonzalo A. Alvarez, Ernesto P. Danieli, Patricia R. Levstein +1
An environment interacting with portions of a system leads to multiexponential interaction rates. Within the Keldysh formalism, we fictitiously homogenize the system-environment in…
