Generic long-range correlations in nonequilibrium mixtures
Jessica Metzger, Yariv Kafri, Mehran Kardar +1
We study correlation functions in generic non-equilibrium mixtures, including multi-temperature systems and non-reciprocal field theories. The corresponding linear theory is short-…

How active field theories couple to external potentials
Yariv Kafri, Julien Tailleur
We study the simplest terms that need to be included in active field theories to couple them to external potentials. To do so, we consider active Brownian particles and implement a…

How Continuous Symmetry Stabilizes the Ordered Phase of Polar Flocks
Omer Granek, Hugues Chaté, Yariv Kafri +3
We study the stability of the ordered phase of compressible polar flocks against the nucleation of counter-propagating droplets, using a combination of analytical theory, microscop…
