Dynamics of active run and tumble and passive particles in binary mixture
Vivek Semwal, Jay Prakash, Shradha Mishra
We study a binary mixture of disk-shaped {\it active run and tumble } particles () and passive particles on a two-dimensional substrate. Both types of particles are atherm…
Ordering through learning in two-dimensional Ising spins
Pranay Bimal Sampat, Ananya Verma, Riya Gupta +1
We study two-dimensional Ising spins, evolving through reinforcement learning using their state, action, and reward. The state of a spin is defined as whether it is in the majority…
Activity Driven Phase Separation and Ordering Kinetics of Passive Particles
Shambhavi Dikshit, Shradha Mishra
The steady state and phase ordering kinetics in a pure active Borwnian particle system are studied in recent years. In binary mixture of active and passive Brownian particles passi…
Domain Growth in the Active Model B: Critical and Off-critical Composition
Sudipta Pattanayak, Shradha Mishra, Sanjay Puri
We study the ordering kinetics of an assembly of {\it active Brownian particles} (ABPs) on a two-dimensional substrate. We use a coarse-grained equation for the composition order p…
Inhomogeneous activity enhances density phase separation in active model B
Ajeya Krishna, Shradha Mishra
We study the binary phase separation in active model B, on a two-dimensional substrate with inhomogeneous activity. The activity was introduced with a maximum value at the center o…
Bond disorder enhances the information transfer in polar flock
Jay Prakash Singh, Sameer Kumar, Shradha Mishra
Collection of self-propelled particles (SPPs) exhibit coherent motion and show true long-range order in two-dimensions. Inhomogeneity, in general destroys the usual long-range orde…
Ordering Kinetics in the Active Model B
Sudipta Pattanayak, Shradha Mishra, Sanjay Puri
We undertake a detailed numerical study of the {\it Active Model B} proposed by Wittkowski et al. [Nature Comm. {\bf 5}, 4351 (2014)]. We find that the introduction of activity has…
Effect of polydispersity on the dynamics of active Brownian particles
Sameer Kumar, Jay Prakash Singh, Debaprasad Giri +1
We numerically study the dynamics and the phases of self-propelled disk-shaped particles of different sizes with soft repulsive potential in two dimensions. Size diversity is intro…
Polar swimmers induce several phases in active nematics
Pranay Bimal Sampat, Shradha Mishra
Swimming bacteria in passive nematics in the form of lyotropic liquid crystals are defined as a new class of active matter known as living liquid crystals in recent studies. It has…
