Motility destabilizes an absorbing-state flock
Narayan Dutt Sharma, Subroto Mukerjee, Chandan Dasgupta +1
Activity, when it takes the form of motility, is generally seen to promote order in many-body systems. Here we present a one-dimensional lattice model that, in the non-motile limit…
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…
Conservation laws and chaos propagation in a non-reciprocal classical magnet
Nisarg Bhatt, Purnendu Das, Subroto Mukerjee +1
We study a nonreciprocal generalization [EPL 60, 418 (2002)] of the classical Heisenberg spin chain, in which the exchange coupling is nonsymmetric, and show that it displays a bal…
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…
