Dynamic renormalization of scalar active field theories
Nikos Papanikolaou, Thomas Speck
We study Active Model B+, a scalar field theory extending the paradigmatic Model B for equilibrium coexistence through including terms that do not arise from an underlying free ene…

Perturbative dynamic renormalization of scalar field theories in statistical physics
Nikos Papanikolaou, Thomas Speck
Renormalization is a powerful technique in statistical physics to extract the large-scale behavior of interacting many-body models. These notes aim to give an introduction to pertu…
