- Abstract: We study the effect of correlation on the direction of particle exchange
between local thermal sub-systems where the total system is isolated. Our focus
is the situation where both sub-systems have the same temperature but different
chemical potentials to eliminate the effect of energy transfer due to the
temperature difference. The analysis is done in two limits; in the short time
scale where the final state of each sub-system is close to its initial thermal
state and in a longer time scale where each sub-system's final state can be
arbitrary. The results indicate that the conventional flow of particles from a
higher chemical potential to a lower one occurs when the correlation which is
quantified by mutual information increases. In contrast, an anomalous flow of
particles in the reverse direction has a chance to happen when the correlation
goes down. Our findings show that the direction of the particle exchange cannot
be predetermined by the chemical potential difference in the presence of
correlation.

We study the entanglement properties of free fermions on a one-dimensional lattice that contains a generic charge- and energy-conserving noninteracting impurity.
We show that all these measures scale linearly with the overlap between one subsystem and the mirror image of the other.
While a simple proportionality relation between the negativity and R'enyi versions of the mutual information is observed to hold at zero temperature, it breaks down at finite temperatures.

In particular we describe how the probability distribution of the former shows different behaviour in the area-law and volume-law regimes.

We develop an alternative theoretical framework for the thermodynamic analysis of two-level systems.
We observe the appearance of a new term of work, which represents the energy cost of rotating the Bloch vector in presence of the external field that defines the local Hamiltonian.
In order to illustrate our findings we study, from both perspectives, matter-radiation interaction processes for two different systems.

We focus on correlation functions associated with the antisymmetric and symmetric combinations of the two TLLs.
The presence of different speeds of sound leads to multiple lightcones separating different decaying regimes.

We study a two level system coupled to a first thermal reservoir that in turn couples to a second thermal bath at a different temperature.
We observe prethermalization, a transitory phenomenon in which the system initially approaches thermal equilibrium with respect to the first reservoir.
In this case, the energy current through the system may exhibit transient features and even switch direction, before the system eventually reaches a non-equilibrium steady state.
