Quasi-normal modes of a strongly coupled non-conformal plasma and approach to criticality
Panagiotis Betzios, Umut Gürsoy, Matti Järvinen +1
We study fluctuations around equilibrium in a class of strongly interacting non-conformal plasmas using holographic techniques. In particular we calculate the quasi-normal mode spe…
