"In this work, a framework for the computation of the time evolution of\r\ncorrelation functions is developed. For that purpose, techniques from the\r\nfunctional renormalisation group (fRG) are used, with the unique feature of a\r\ntemporal regulator. This specific choice of regulator suppresses quantum\r\nfluctuations based on a time scale and yields causal properties for correlation\r\nfunctions. As a consequence, flow equations can always be integrated\r\nanalytically, which in turn allows for the derivation of a one-loop exact\r\nfunctional relation for the inverse propagator. In addition to this formal\r\nresult, the method is applied to the phi^3-theory, where the dynamics of the\r\npropagator is investigated. In this setup, the system is prepared\r\nfar-from-equilibrium and the time evolution of the propagator is computed. Even\r\nin the simple truncation that is employed, there are already hints at a\r\nself-similar time evolution.\r\n\r\nIn a separate part, three-dimensional Yang-Mills theory is examined in\r\nequilibrium. Due to the simpler computation as opposed to non-equilibrium\r\nscenarios, it is possible to investigate this theory in view of different\r\ntruncations. This study reveals that truncations have to be chosen carefully in\r\norder to achieve apparent convergence."^^ . "2021" . . . . . . . "Lukas"^^ . "Corell"^^ . "Lukas Corell"^^ . . . . . .
