Field-theoretical modeling of a zombie apocalypse* — •Michael te Vrugt¹, Julian Jeggle², and Raphael Wittkowski² — ¹DAMTP, Centre for Mathematical Sciences, University of Cambridge, Cambridge CB3 0WA, United Kingdom — ²Institut für Theoretische Physik, Center for Soft Nanoscience, Universität Münster, 48149 Münster, Germany

The physics of systems with nonreciprocal interactions has attracted a significant amount of interest in recent years. A prototypical example are predator-prey systems. In this work [1], we connect the physics of nonreciprocal interactions to epidemiology by developing a dynamical density functional theory for a popular hypothetical infectious disease, namely a zombie outbreak. A numerical investigation of this model is used to compare different strategies for containing the spread of zombies.
