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…
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…
Revisiting the Ratchet Principle: When Hidden Symmetries Prevent Steady Currents
Jessica Metzger, Sunghan Ro, Julien Tailleur
The "ratchet principle", which states that non-equilibrium systems violating parity symmetry generically exhibit steady-state currents, is one of the few generic results outside th…
Mechanical pressure and momentum conservation in dry active matter
Yaouen Fily, Yariv Kafri, Alexandre P. Solon +2
We relate the breakdown of equations of states for the mechanical pressure of generic dry active systems to the lack of momentum conservation in such systems. We show how sources a…
