Velocity Resetting of Inertial Run-and-Tumble Particles in Non-Newtonian Media: Velocity Distribution, Diffusion and First-Passage Time
Subhanker Howlader, Sayantan Mondal, Prasenjit Das
We study the dynamics of an athermal inertial run-and-tumble particle moving through a non-Newtonian medium in , where the particle's velocity is reset to zero at a consta…
Derivation and Analysis of Amplitude Equation for Generalized AMB+ in Presence of Chemical Reaction
Sayantan Mondal, Prasenjit Das
We derive and analyze the amplitude equation for the roll patterns in case of generalized Active Model B+ (AMB+) in the presence of chemical reactions. The generalized AMB+ differs…
Velocity Distribution and Diffusion of an Athermal Inertial Run-and-Tumble Particle in a Shear-Thickening Medium
Subhanker Howlader, Sayantan Mondal, Prasenjit Das
We study the dynamics of an athermal inertial run-and-tumble particle moving in a shear-thickening medium in . The viscosity of the medium is represented by a nonlinear functi…
Ultraslow Growth of Domains in a Random-Field System With Correlated Disorder
Subhanker Howlader, Prasenjit Das, Manoj Kumar
We study domain growth kinetics in a random-field system in the presence of a spatially correlated disorder after an instantaneous quench at a finite temperature $T…
Phase Separation in Active Binary Mixtures With Chemical Reaction
Sayantan Mondal, Prasenjit Das
We study motility-induced phase separation~(MIPS) in active AB binary mixtures undergoing the chemical reaction . Starting from the evolution equations for…
Velocity Distribution and Diffusion of an Athermal Inertial Run-and-Tumble Particle in a Shear-Thinning Medium
Sayantan Mondal, Prasenjit Das
We study the dynamics of an athermal inertial active particle moving in a shear-thinning medium in . The viscosity of the medium is modeled using a Coulomb-tanh function, whil…
