- 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.

Common intuition tells us that if one part of a connected system is cooled continuously, the other parts should also cool down.
We show that by suppressing resonant energy exchange between the two parts, one can reverse the fate of the system.
Our findings highlight the critical role played by the nature of the coupling and reveal a rich interplay between symmetry and resonance effects in the dynamics of thermalization.

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.

We focus on correlation functions associated with the antisymmetric and symmetric combinations of the two TLLs.
