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…
When evolution realizes large deviations of fitness: from speciation to dynamical phase transitions
Sara Dal Cengio, Quentin Laurenceau, Vivien Lecomte +2
We explore the connection between evolution and large-deviation theory. To do so, we study evolutionary dynamics in which individuals experience mutations, reproduction, and select…
Exceptions to the Ratchet Principle in active and passive stochastic dynamics
Jessica Metzger, Sunghan Ro, Julien Tailleur
The "ratchet principle" asserts that non-equilibrium systems which violate parity symmetry generically exhibit steady-state currents. As recently shown, there are exceptions to thi…
Statistical mechanics of a cold tracer in a hot bath
Amer Al-Hiyasat, Sunghan Ro, Julien Tailleur
We study the dynamics of a zero-temperature particle interacting linearly with a bath of hot Brownian particles. Starting with the most general model of a linearly-coupled bath, we…
A Cold Tracer in a Hot Bath: In and Out of Equilibrium
Amer Al-Hiyasat, Sunghan Ro, Julien Tailleur
We study the dynamics of a zero-temperature overdamped tracer in a bath of Brownian particles. As the bath density is increased, numerical simulations show the tracer to transition…
