Quantum Markovian master equation in the high-temperature limit
Ricardo C. Zamar, J. Agustín Taboada
We present a critical derivation of the high-temperature quantum Markovian master equation (HTME), examining its foundational assumptions, their quantum-mechanical implications, an…
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…
Irreversible decoherence of dipole interacting nuclear spins coupled with a phonon bath
F. D. Domínguez, C. E. González, H. H. Segnorile +1
We report a first-principle theoretical study of the adiabatic decoherence undergone by a nuclear spin system in a solid, coupled to the phonon field through the dipolar interactio…
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…
