Equilibrium statistical mechanics rests on the assumption of chaotic dynamics of a system
modulo the conservation laws of local observables: extremization of entropy immediately …

Inspired by holographic Wilsonian renormalization, we consider coarse graining a quantum
system divided between short-distance and long-distance degrees of freedom (dof), coupled …

A bstract We show that for cubic scalar field theories in five and more spacetime dimensions,
and for the T= 0 limit of the Caldeira-Leggett model, the quantum master equation for long …

In most interacting many-body systems associated with some “emergent phenomena,” we
can identify subgroups of degrees of freedom that relax on dramatically different time scales …

We investigate a class of nonequilibrium media described by Langevin dynamics that
satisfies the local detailed balance. For the effective dynamics of a probe immersed in the …

In this work, I consider the possibility of using typicality-type arguments for understanding
intractably complex damped-driven dynamical systems. By approximating such dynamics …

In this thesis, we started an exploration of various different aspects of quantum field theories
in which the presence of entanglement between field degrees of freedom plays an essential …
