Correction to the geometric phase by structured environments: The onset of non-Markovian effects
(American Physical Society, 2015-04)
We study the geometric phase of a two-level system under the presence of a structured environment, particularly analyzing its correction with the ohmicity parameter s and the onset of non-Markovianity. We first examine the ...
Markovian versus non-Markovian stochastic quantization of a complex-action model
(World Scientific Publ Co Pte Ltd, 2014-03-10)
We analyze the Markovian and non-Markovian stochastic quantization methods for a complex action quantum mechanical model analog to Maxwell-Chern-Simons electrodynamics in Weyl gauge. We show through analytical methods ...
Quantum Non-Markovian Processes Break Conditional Past-Future Independence
(American Physical Society, 2018-12)
For classical Markovian stochastic systems, past and future events become statistically independent when conditioned to a given state at the present time. Memory non-Markovian effects break this condition, inducing a ...
Non-Markovian quantum jumps from measurements in bipartite Markovian dynamics
(American Physical Society, 2013-07)
The quantum jump approach allows to characterize the stochastic dynamics associated with an open quantum system submitted to a continuous measurement action. In this paper we show that this formalism can consistently be ...
Embedding non-Markovian quantum collisional models into bipartite Markovian dynamics
(American Physical Society, 2013-09-25)
A wide class of non-Markovian completely positive master equations can be formulated on the basis of quantum collisional models. In this phenomenological approach the dynamics of an open quantum system is modeled through ...
Driving-induced amplification of non-Markovianity in open quantum systems evolution
(Europhysics Letters, 2017-04)
Non-Markovian effects arising in open quantum system evolution have been a subject of increasing interest over the past decade. One of the most appealing features of non-Markovianity (NM) is that it captures scenarios where ...
Perturbation theory for operational quantum non-Markovianity
(American Physical Society, 2020-08-19)
The definition of memory in operational approaches to quantum non-Markovianity depends on the statistical properties of different sets of outcomes related to successive measurement processes performed over the system of ...
Estimating the degree of non-Markovianity using machine learning
(2021-02-01)
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 ...
Quantum-speed-limit bounds in an open quantum evolution
(American Physical Society, 2016-11)
ABSTRACTQuantum mechanics dictates bounds for the minimal evolution time between predetermined initial and final states. Several of these quantum-speed-limit (QSL) bounds were derived for nonunitary dynamics using different ...
