Entropy production and correlations in a controlled non-Markovian setting

  title={Entropy production and correlations in a controlled non-Markovian setting},
  author={Maria Popovic and Bassano Vacchini and Steve Campbell},
  journal={Physical Review A},
We study the relationship between (non-)Markovian evolutions, established correlations, and the entropy production rate. We consider a system qubit in contact with a thermal bath and in addition the system is strongly coupled to an ancillary qubit. We examine the steady-state properties finding that the coupling leads to effective temperatures emerging in the composite system, and show that this is related to the creation of correlations between the qubits. By establishing the conditions under…

We investigate the irreversible entropy production of a qubit in contact with an environment modelled by a microscopic collision model in both Markovian and non-Markovian regimes. Our main goal is to

Non-Markovianity and negative entropy production rates.

This work shows under which conditions a negative entropy production rate implies non-Markovianity and when it does not, and provides a consistent theoretical framework to study the finite-time thermodynamics of a large class of dynamics with a precise link to its non- Markovianicity.

Positive entropy production rate induced by non-Markovianity

The non-Markovian effect on entropy production rate is an open question in quantum thermodynamics. By means of the change rate of the trace distance as the witness, we explore the non-Markovianities

System-environment correlations and Markovian embedding of quantum non-Markovian dynamics

We study the dynamics of a quantum system whose interaction with an environment is described by a collision model, i.e., the open dynamics is modeled through sequences of unitary interactions between

Coherence and entropy squeezing in the spin-boson model under non-Markovian environment

We study the dynamical behavior of the coherence and squeezing for a two-level system immersed in an environment modeled by a spin degree of freedom in a magnetic field coupled linearly to an

Non-Markovianity and the Landauer principle in composite thermal environments

We study non-Markovianity and the Landauer principle in a composite thermal environment consisting of a memory dissipated to a Markovian reservoir. We consider non-Markovianity with respect to four

Effect of entanglement embedded in environment on quantum non-Markovianity based on collision model

By means of collision models (CMs) where the environment is simulated by a collection of ancillas consisting of two entangled qubits, we investigate the effects of entanglement in the environment on



Thermodynamic fingerprints of non-Markovianity in a system of coupled superconducting qubits

The exploitation and characterization of memory effects arising from the interaction between system and environment is a key prerequisite for quantum reservoir engineering beyond the standard

Entropy production as correlation between system and reservoir

We derive an exact (classical and quantum) expression for the entropy production of a finite system placed in contact with one or several finite reservoirs, each of which is initially described by a

Entropy production and non-Markovian dynamical maps

It is shown that, when the conditions leading to reduced dynamics of semigroup type are relaxed, a consistent formulation of the second law of thermodynamics requires that the environment contribution to the entropy balance be explicitly taken into account.

Entanglement and non-markovianity of quantum evolutions.

Two different measures of non-markovianity are introduced that exploit the specific traits of quantum correlations and are suitable for opposite experimental contexts when complete tomographic knowledge about the evolution is available and when no information whatsoever is available.

The role of coherence in the non-equilibrium thermodynamics of quantum systems

Exploiting the relative entropy of coherence, we isolate the coherent contribution in the energetics of a driven non-equilibrium quantum system. We prove that a division of the irreversible work can

Thermodynamic irreversibility is well characterized by the entropy production arising from non-equilibrium quantum processes. We show that the entropy production of a quantum system undergoing

Comparative study of non-Markovianity measures in exactly solvable one- and two-qubit models

In this paper we present a detailed critical study of several recently proposed non-Markovianity measures. We analyse their properties for single qubit and two-qubit systems in both pure-dephasing

Foundations and measures of quantum non-Markovianity

Mixing dynamical maps describing open quantum systems can lead from Markovian to non-Markovian processes. Being surprising and counter-intuitive, this result has been used as argument against

We investigate the fundamental limitations imposed by thermodynamics for creating correlations. Considering a collection of initially uncorrelated thermal quantum systems, we ask how much classical
