Motion of a Polymer Globule with Vicsek-like Activity: From Super-diffusive to Ballistic Behavior
Subhajit Paul, Suman Majumder, Wolfhard Janke
Via molecular dynamics simulation with Langevin thermostat we study the structure and dynamics of a flexible bead-spring active polymer model after a quench from good to poor solve…
Dependence of Cluster Growth on Coefficient of Restitution in a Cooling Granular Fluid
Subir K. Das, Subhajit Paul
Starting from configurations having homogeneous spatial density, we study kinetics in a two-dimensional system of inelastically colliding hard particles, a popular model for coolin…
How Do Clusters in Phase-Separating Active Matter Systems Grow? A study for Vicsek activity in systems undergoing vapor-solid transition
Subhajit Paul, Arabinda Bera, Subir K. Das
Via molecular dynamics simulations we have studied kinetics of vapor-"solid" phase transition in an active matter model in which self-propulsion is introduced via the well-known Vi…
Initial Correlation Dependence of Aging in Phase Separating Solid Binary Mixtures and Ordering Ferromagnets
Subir K. Das, Koyel Das, Nalina Vadakkayil +2
Following quenches of initial configurations having long range spatial correlations, prepared at the demixing critical point, to points inside the miscibility gap, we study aging p…
