- Abstract: We examine the transmission of quantum particles (phonons, electrons, and
photons) across interfaces, identifying universal patterns in diverse physical
scenarios. Starting with classical wave equations, we quantize them and derive
kinetic equations. Those are matching conditions for the distribution functions
of particles at the interface. We note the time irreversibility of the derived
kinetic equations -- an essential feature for accurately describing
irreversible processes like heat transport. We identify the juncture in our
derivation where the time symmetry of wave equations is disrupted, it is the
assumption of the non-coherence of incident waves. Consequently, we infer that
non-coherent transmission through the interface exhibits time irreversibility.
We propose an experiment to validate this hypothesis.

We define a quantum pressure, a quantum temperature and a quantum internal energy which are related to each other in the same fashion as in the classical kinetic theory.
In the end, we show that the kinetic internal energy is linked to the fractional transformer part of the underlying classical dynamics.

How a finite-temperature environment can localize wave functions is still being debated.
We represent the environment by a fluctuating potential and investigate different unravellings of the Lindblad equation.
We conclude that as long as no feedback between the wave function and the environment is taken into account, there will be no unique description of an open quantum system in terms of wave functions.
