Kinetics of quantum reaction-diffusion systems by Federico Gerbino, Igor Lesanovsky, Gabriele Perfetto

“…In this context, we quantify the irreversibility of the dynamics studying the time evolution of the system entropy for different quenches of the trapping potential. …”

From Quantum Unstable Systems to the Decaying Dark Energy: Cosmological Implications by Aleksander Stachowski, Marek Szydłowski, Krzysztof Urbanowski

“…We consider a cosmology with decaying metastable dark energy and assume that a decay process of this metastable dark energy is a quantum decay process. Such an assumption implies among others that the evolution of the Universe is irreversible and violates the time reversal symmetry. …”
