Description
We present our study of non-Markovian effects on the evolution of quarkonia and heavy quarks in the QGP using the framework of open quantum systems. For quarkonia, we set up a general non-Markovian master equation to describe their evolution in the medium, without assuming the quantum Brownian regime. We quantify the effect of the hierarchy between the binding energy and the medium temperature on quarkonium evolution and show that it significantly affects RAA. For the heavy-quark scenario, we derive a non-Markovian master equation in weak coupling within NRQCD. We quantify the timescale over which non-Markovian effects remain important, and their relative difference compared to the Markovian limit. Connection to the Langevin formalism is made through the calculation of time dependant transport coefficients.
