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…
Roughening of two-dimensional interfaces in nonequilibrium phase-separated systems
John Toner
I show that non-equilibrium two-dimensional interfaces between three dimensional phase separated fluids exhibit a peculiar "sub-logarithmic" roughness. Specifically, an interface o…
Broken living layers: dislocations in active smectics
Frank Julicher, Jacques Prost, John Toner
We show that dislocations in active 2d smectics with underlying rotational symmetry are always unbound in the presence of noise, meaning the active smectic phase does not exist for…
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…
Incompressible polar active fluids with quenched disorder in dimensions
Leiming Chen, Chiu Fan Lee, Ananyo Maitra +1
We present a hydrodynamic theory of incompressible polar active fluids with quenched disorder. This theory shows that such fluids can overcome the disruption caused by the quenched…
Packed swarms on dirt: two-dimensional incompressible flocks with quenched and annealed disorder
Leiming Chen, Chiu Fan Lee, Ananyo Maitra +1
We show that incompressible polar active fluids can exhibit an ordered, coherently moving phase even in the presence of quenched disorder in two dimensions. Unlike such active flui…
