Non-Markovian quantum dynamics and classical chaos
(American Physical Society, 2012-08)
We study the influence of a chaotic environment in the evolution of an open quantum system. We show that there is an inverse relation between chaos and non-Markovianity. In particular, we remark on the deep relation of the ...
Coherent control of an effective two-level system in a non-Markovian biomolecular environment
(2009-08)
We investigate the quantum coherent dynamics of an externally driven effective two-level system (TLS) subjected to a slow Ohmic environment characteristic of biomolecular protein–solvent reservoirs in photosynthetic ...
Estimating the degree of non-Markovianity using machine learning
(AMER PHYSICAL SOC, 2021-02-24)
In the last few years, the application of machine learning methods has become increasingly relevant in different fields of physics. One of the most significant subjects in the theory of open quantum systems is the study ...
Inequivalence of correlation-based measures of non-Markovianity
(2016-09-06)
We conclusively show that the entanglement- and the mutual-information-based measures of quantum non-Markovianity are inequivalent. To this aim, we first analytically solve the optimization problem in the definition of the ...
Conditional past-future correlation induced by non-Markovian dephasing reservoirs
(American Physical Society, 2019-05-28)
Memory effects can be studied through a conditional past-future correlation, which measures departure with respect to a conditional past-future independence valid in a memoryless Markovian regime. In a quantum regime this ...
Enhancement of quantum correlations and a geometric phase for a driven bipartite quantum system in a structured environment
(American Physical Society, 2021-03)
We study the role of driving in an initial maximally entangled state evolving under the presence of a structured environment in a weak and strong regime. We focus on the enhancement and degradation of maximal concurrence ...
Non-Markovian damping of Rabi oscillations in semiconductor quantum dots
(Iop Publishing LtdBristolInglaterra, 2009)
Memory effects in superfluid vortex dynamics
(Springer/Plenum Publishers, 2004-11)
The dissipative dynamics of a vortex line in a superfluid is investigated within the frame of a non-Markovian quantal Brownian motion model. Our starting point is a recently proposed interaction Hamiltonian between the ...
Dynamical memory effects in correlated quantum channels
(Amer Physical Soc, 2016-09-23)
Memory effects play a fundamental role in the study of the dynamics of open quantum systems. There exist two conceptually distinct notions of memory discussed for quantum channels in the literature. In quantum information ...
