Work to insert a particle into an active fluid
Freddy A. Cisneros, Alexandre Solon, Jordan M. Horowitz
The chemical potential is defined as the work to quasi-statically add a particle to an equilibrium system. Inspired by this definition, we investigate how the work to add a particl…
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…
Continuing the discussion on "The inconvenient truth about flocks" by Chen et al
Hugues Chaté, Alexandre Solon
We hereby reply concisely and hopefully clearly to the ongoing claims of incorrectness made by Chen et al. about our work on two-dimensional flocks.
Comment on "The inconvenient truth about flocks" by Chen et al
Hugues Chaté, Alexandre Solon
We hope here to provide the community with a convenient account of our viewpoint on the claims made by Chen et al. about our results on two-dimensional polar flocks.
Inescapable anisotropy of non-reciprocal XY models
Dawid Dopierala, Hugues Chaté, Xia-qing Shi +1
We investigate non-reciprocal XY (NRXY) models defined on two-dimensional lattices in which the coupling strength of a spin with its neighbors varies with their position in the fra…
