True and Quasi Long-Range Order in Malthusian Flocks

Patrick Jentsch, Anna Erzberger

Living matter undergoes continuous turnover. The hydrodynamic theory of Malthusian flocks describes polar active matter with turnover, but its phase diagram and nonlinear scaling b…

Hydrodynamics, Renormalization Group, and Universality Classes Far from Equilibrium

Patrick Jentsch, Chiu Fan Lee

Universality is one of the central organising principles of modern physics, explaining why systems with vastly different microscopic constituents can exhibit identical large-scale…

Diversity of critical phenomena in the ordered phase of polar active fluids

Patrick Jentsch, Chiu Fan Lee

We present a comprehensive analytical linear stability analysis of the Toner-Tu model for polar active fluids in the ordered phase. Our results provide exact instability criteria a…

The inconvenient truth about flocks

Leiming Chen, Patrick Jentsch, Chiu Fan Lee +3

We reanalyze the hydrodynamic theory of "flocks" that is, polar ordered "dry" active fluids in two dimensions. For "Malthusian" flocks, in which birth and death cause the density t…

Can exact scaling exponents be obtained using the renormalization group? Affirmative evidence from incompressible polar active fluids

Patrick Jentsch, Chiu Fan Lee

In active matter systems, non-Gaussian, exact scaling exponents have been claimed in a range of systems using perturbative renormalization group (RG) methods. This is unusual compa…

Novel critical phenomena in compressible polar active fluids: Dynamical and Functional Renormalization Group Studies

Patrick Jentsch, Chiu Fan Lee

Active matter is not only relevant to living matter and diverse nonequilibrium systems, but also constitutes a fertile ground for novel physics. Indeed, dynamic renormalization gro…

Physical properties of the massive Schwinger model from the nonperturbative functional renormalization group

Patrick Jentsch, Romain Daviet, Nicolas Dupuis +1

We investigate the massive Schwinger model in dimensions using bosonization and the nonperturbative functional renormalization group. In agreement with previous studies we…
