Quasi-equilibrium and quantum correlation in an open spin-pair system
J. A. Taboada, H. H. Segnorile, C. E. González +1
Quasi-equilibrium states that can be prepared in solids through Nuclear Magnetic Resonance (NMR) techniques are out-of-equilibrium states that slowly relax towards thermodynamic eq…
Adiabatic quantum decoherence in many non-interacting subsystems induced by the coupling with a common boson bath
H. H. Segnorile, C. E. González, R. C. Zamar
This work addresses quantum adiabatic decoherence of many-body spin systems coupled with a boson field in the framework of open quantum systems theory. We generalize the traditiona…
Mechanisms of irreversible decoherence in solids
Federico Daniel Domínguez, Ricardo César Zamar, Héctor Hugo Segnorile +1
Refocalization sequences in Nuclear Magnetic Resonance (NMR) can in principle reverse the coherent evolution under the secular dipolar Hamiltonian of a closed system. We use this e…
Evolution towards quasi-equilibrium in nematic liquid crystals studied through decoherence of multi-spin multiple-quantum coherences
H. H. Segnorile, C. E. González, R. C. Zamar
New evidence is presented in favor of irreversible decoherence as the mechanism which leads an initial out-of-equilibrium state to quasi-equilibrium in nematic liquid crystals. The…
