Hydrodynamic Theory of Two-dimensional Chiral Malthusian Flocks
Leiming Chen, Chiu Fan Lee, John Toner
We study the hydrodynamic behavior of two-dimensional chiral dry Malthusian flocks; that is, chiral polar-ordered active matter with neither number nor momentum conservation. We sh…
Only the Ambidextrous Can Flock: Two-dimensional Chiral Malthusian Flocks, Time Cholesterics, and the KPZ Equation
Leiming Chen, Chiu Fan Lee, John Toner
We study two-dimensional chiral dry Malthusian flocks; that is, chiral polar-ordered active matter with neither number nor momentum conservation. In the absence of fluctuations, th…
Response to the comment on The inconvenient truth about flocks by Chaté and Solon
Leiming Chen, Patrick Jentsch, Chiu Fan Lee +3
This is our response to the comment arXiv:2504.13683 posted by Chaté and Solon in reference to our preprint arXiv:2503.17064
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…
Dynamics of packed swarms: time-displaced correlators of two dimensional incompressible flocks
Leiming Chen, Chiu Fan Lee, Ananyo Maitra +1
We analytically calculate the scaling exponents of a two-dimensional KPZ-like system: coherently moving incompressible polar active fluids. Using three different renormalization gr…
Hydrodynamic theory of two-dimensional incompressible polar active fluids with quenched and annealed disorder
Leiming Chen, Chiu Fan Lee, Ananyo Maitra +1
We study the moving phase of two-dimensional (2D) incompressible polar active fluids in the presence of both quenched and annealed disorder. We show that long-range polar order per…
