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…
Non-reciprocal interactions drive emergent chiral crystallites
S. J. Kole, Xichen Chao, Abraham Mauleon-Amieva +3
We study a new type of 2D active material that exhibits macroscopic phases with two emergent broken symmetries: self-propelled achiral particles that form dense hexatic clusters, w…
Chirality and odd mechanics in active columnar phases
S. J. Kole, Gareth P. Alexander, Ananyo Maitra +1
Chiral active materials display odd dynamical effects in both their elastic and viscous responses. We show that the most symmetric mesophase with two-dimensional odd elasticity in…
Omnidirectional transport and navigation of Janus particles through a nematic liquid crystal film
Dinesh Kumar Sahu, Swapnil Kole, Sriram Ramaswamy +1
We create controllable active particles in the form of metal-dielectric Janus colloids which acquire motility through a nematic liquid crystal film by transducing the energy of an…
