We analyse the role played by system-environment correlations in the emergence of non-Markovian dynamics. By working within the framework developed in Breuer et al., Phys. Rev. Lett. 103, 210401 (2009), we unveil a fundamental connection between non-Markovian behaviour and dynamics of system-environment correlations. We derive an upper bound to the rate of change of the distinguishability between different states of the system that explicitly depends on the development and establishment of…

Implications of non-Markovian quantum dynamics for the Landauer bound
We study the dynamics of a spin-1/2 particle interacting with a multi-spin environment, modelling the corresponding open system dynamics through a collision-based model. The environmental particles
Interaction-induced correlations and non-Markovianity of quantum dynamics
We investigate the conditions under which the trace distance between two different states of a given open system increases in time due to the interaction with an environment, therefore signaling
Entropy Production in Non-Markovian Collision Models: Information Backflow vs. System-Environment Correlations
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
Precursors of non-Markovianity
Using the paradigm of information backflow to characterize a non-Markovian evolution, we introduce so-called precursors of non-Markovianity, i.e. necessary properties that the system and environment
Positivity in the presence of initial system-environment correlation
The constraints imposed by the initial system-environment correlation can lead to nonpositive dynamical maps. We find the conditions for positivity and complete positivity of such dynamical maps by
Markovianity of an emitter coupled to a structured spin-chain bath
We analyze the dynamics of a spin 1/2 subsystem coupled to a spin chain. We simulate numerically the full quantum many-body system for various sets of parameters and initial states of the chain, and
Irreversibility at zero temperature from the perspective of the environment
We address the emergence of entropy production in the non-equilibrium process of an open quantum system from the viewpoint of the environment. By making use of a dilation-based approach akin to
Effects of the rotating wave and secular approximations on non-Markovianity
We study the effect of the rotating-wave approximation (RWA) and the secular approximation (SA) on the non-Markovian behavior in the spin-boson model at zero-temperature. We find that both the RWA
Linear Optics Simulation of Quantum Non-Markovian Dynamics
The experimental realisation of a non-Markovian process where system and environment are coupled through a simulated transverse Ising model is reported and the role played by system-environment correlations in the emergence of memory effects is demonstrated.
On the connection between microscopic description and memory effects in open quantum system dynamics
This analysis clarifies how the interplay between system-environment correlations and environmental-state distinguishability can lead to the same information flow from and toward the open system, despite significant qualitative and quantitative differences at the level of the global evolution.
