Transmissibility in Interactive Nanocomposite Diffusion: The Nonlinear Double-Diffusion Model
Amit K Chattopadhyay, Bidisha Kundu, Sujit Kumar Nath +1
Model analogies and exchange of ideas between physics or chemistry with biology or epidemiology have often involved inter-sectoral mapping of techniques. Material mechanics has ben…
Brownian motion under intermittent harmonic potentials
Ion Santra, Santanu Das, Sujit Kumar Nath
We study the effects of an intermittent harmonic potential of strength -- that switches on and off stochastically at a constant rate , on an overdamped Brownian parti…
Infection Kinetics of Covid-19: Is Lockdown a Potent Containment Tool?
Amit k Chattopadhyay, Debajyot Choudhury, Goutam Ghosh +2
Covid-19 is raging a devastating trail with the highest mortality-to-infected ratio ever for a pandemic. Lack of vaccine and therapeutic has rendered social exclusion through lockd…
A pure hydrodynamic instability in shear flows and its application to astrophysical accretion disks
Sujit Kumar Nath, Banibrata Mukhopadhyay
We provide the possible resolution for the century old problem of hydrodynamic shear flows, which are apparently stable in linear analysis but shown to be turbulent in astrophysica…
Emergence of nonlinearity and plausible turbulence in accretion disks via hydromagnetic transient growth faster than magnetorotational instability
Sujit K. Nath, Banibrata Mukhopadhyay
We investigate the evolution of hydromagnetic perturbations in a small section of accretion disks. It is known that molecular viscosity is negligible in accretion disks. Hence, it…
