Effect of Added Salts on the Interfacial Dynamics of Monovalent Metal Ions and Model Water-Soluble Polymers
Soumik Ghosh, Jack F. Douglas, Francis W. Starr
Traditional theories of electrolyte and polyelectrolyte solutions overlook ion and polymer hydration, yielding an overly idealized perspective of the thermodynamic and dynamic prop…
Coarsening in the Long-range Ising Model with Conserved Dynamics
Soumik Ghosh, Subir K. Das
While the kinetics of domain growth, even for conserved order-parameter dynamics, is widely studied for short-range inter-particle interactions, systems having long-range interacti…
Simulations of Mpemba Effect in WATER, Lennard-Jones and Ising Models: Metastability vs Critical Fluctuations
Soumik Ghosh, Purnendu Pathak, Sohini Chatterjee +1
Via molecular dynamics simulations we study ICE formation in the TIP4P/Ice model that is known to describe structure and dynamics in various phases of WATER accurately. For this pu…
Mpemba Effect and Superuniversality across Orders of Magnetic Phase Transition
Sohini Chatterjee, Soumik Ghosh, Nalina Vadakkayil +3
The quicker freezing of hotter water, than a colder sample, when quenched to a common lower temperature, is referred to as the Mpemba effect (ME). While this counter-intuitive fact…
