Two-Stage Ordering Kinetics in Binary Mixtures of Ellipsoidal Particles
Parameshwaran A, Sanjay Puri, Bhaskar Sen Gupta
We investigate the nonequilibrium phase-ordering kinetics of a binary mixture of uniaxial ellipsoidal particles interacting via the anisotropic Gay-Berne potential using large-scal…
Suppression of Active Super-Diffusion: Impact of String Defects and Canted Multi-Domains
Ritik Rajak, Manish Agarwal, Sanjay Puri +1
We investigate the transport dynamics of an active Brownian particle (ABP) traversing a complex, non-Newtonian liquid crystal (LC) matrix. Employing the Generalized Lebwohl-Lasher…
Violation of the Fluctuation Dissipation Theorem during Domain Growth in the Long-range Ising Model
Parbati Saha, Sanjay Puri, Varsha Banerjee
The celebrated {\it fluctuation dissipation theorem} (FDT) does not apply to nonequilibrium systems. In this context, Cugliandolo and Kurchan [Phys. Rev. Lett. {\bf 71}, 173 (1993)…
Self-assembly of Dipolar Crystals from Magnetic Colloids
Anuj Kumar Singh, Sanjay Puri, Varsha Banerjee
We study the self-assembly of magnetic colloids using the Stockmayer (SM) model characterized by short-range Lennard-Jones interactions and long-range dipole-dipole interactions. U…
Coarsening in Bent-core Liquid Crystals: Intermediate Splay Bend State en route to the Twist Bend Phase
Nishant Birdi, Nigel B. Wilding, Sanjay Puri +1
We use molecular dynamics simulations to study coarsening dynamics in achiral banana-shaped bent-core liquid crystals following a quench from the high concentration polar smectic (…
Surface-directed Dynamics in Living Liquid Crystals
Aditya Vats, Varsha Banerjee, Sanjay Puri
We study living liquid crystals (LLCs), which are an amalgam of nematic liquid crystals (LCs) and active matter (AM). These LLCs are placed in contact with surfaces which impose pl…
