Dynamics of dissipative Bose-Einstein condensation

Stephan Caspar, Florian Hebenstreit, David Mesterházy +1

We resolve the real-time dynamics of a purely dissipative $s = 1/2$ quantum spin or, equivalently, hard-core boson model on a hypercubic $d$ -dimensional lattice. The considered qua…

Discovering and quantifying nontrivial fixed points in multi-field models

Astrid Eichhorn, Thomas Helfer, David Mesterházy +1

We use the functional renormalization group and the $ε$ -expansion concertedly to explore multicritical universality classes for coupled $⨁_{i} O (N_{i})$ vector-field models in…

From quantum to classical dynamics: The relativistic $O (N)$ model in the framework of the real-time functional renormalization group

David Mesterházy, Jan H. Stockemer, Yuya Tanizaki

We investigate the transition from unitary to dissipative dynamics in the relativistic $O (N)$ vector model with the $λ (φ^{2})^{2}$ interaction using the nonperturbative functional…
