Reentrant melting of scarred odd crystals by self-shear
Uttam Tiwari, Pragya Arora, A K Sood +3
Spatial confinement can induce geometrical frustration in condensed phases, giving rise to topological defects that confer materials with new and exotic properties. Here, we experi…
Segregation dynamics in active-passive mixtures of semiflexible filaments
Chitrak Bhowmik, Aparna Baskaran, Sriram Ramaswamy
We study the segregation of motile semiflexible filaments from a background of similar but non-motile filaments. Our Langevin dynamics simulations reveal a wide range of emergent s…
Edge states, pairing, and sorting of motile chiral particles
Raushan Kant, Ananyo Maitra, A K Sood +1
We present experiments on chiral active polar particles, realised as vibrated granular rods, revealing evidence for ``skipping orbits'' at hard boundaries. These classical edge sta…
Screw Symmetry, Chiral Hydrodynamics and Odd Instability in Active Cholesterics
Gareth P. Alexander, S. J. Kole, Ananyo Maitra +1
Active cholesterics are chiral in both their structure, which has continuous screw symmetry, and their active stresses, which include contributions from torque dipoles. Both expres…
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…
