- Abstract: We investigate the open dynamics of a chain of interacting spins using the
quantized version of the GENERIC equation from classical out-of-equilibrium
thermodynamics. We focus on both equilibrium and nonequilibrium scenarios for
chains of different sizes. While in the equilibrium case we demonstrate thermal
equilibration to the correct many-body Gibbs density matrix, in the
nonequilibrium dynamics we show a ballistic-to-diffusive transition in the
steady-state energy current and a scaling that is consistent with Fourier's law
of heat transfer.

We introduce a non-equilibrium version of the Caldeira-Leggett model in which a quantum particle is strongly coupled to a set of engineered reservoirs.
Strongly displaced/squeezed reservoirs can be used to generate an effective time dependence in the system Hamiltonian.
We show the quantum-classical correspondence between the heat statistics in the non-equilibrium Caldeira-Leggett model and the statistics of a classical Langevin particle under the action of squeezed and displaced colored noises.

We show that an exponential speedup to equilibrium will always occur if the state is transformed to a diagonal state in the energy eigenbasis.
When the transformed state has a higher nonequilibrium free energy, we argue using thermodynamic reasoning that this is a textitgenuine quantum Mpemba effect.

We consider adiabatic quantum pumping through a resonant level model, a single-level quantum dot connected to two fermionic leads.
We develop a self-contained thermodynamic description of this model accounting for the variation of the energy level of the dot and the tunnelling rates with the thermal baths.
