Entropy exchange in an inter-correlating binary quasi-classical system: Concept of entropy-bath accelerated molecular dynamics
Projesh Kumar Roy
This letter highlights the entropy exchange phenomenon in a coupled binary inter-correlating system following Haldane's non-linear statistical correlation. A unique coupling betwee…
Aging of ring polymeric topological glass formers via thermal quench
Arabinda Behera, Projesh Roy, Pinaki Chaudhuri +1
We investigate the dynamical response of glass-forming systems composed of topologically constrained ring polymers subjected to an instantaneous thermal quench, employing large-sca…
Application of Haldane's statistical correlation theory in classical systems
Projesh Kumar Roy
This letter investigates the application of Haldane's statistical correlation theory in classical systems. A modified statistical correlation theory has been proposed by including…
Bidisperse ring polymers: topological glass to stacking
Projesh Kumar Roy, Pinaki Chaudhuri, Satyavani Vemparala
Via large-scale molecular dynamics simulations, we observe the melting of a topological glass of stiff ring polymers by incorporating flexible ring polymers, along an isobaric path…
Influence of the coordination defects on the dynamics and the potential energy landscape of two-dimensional silica
Projesh Kumar Roy, Andreas Heuer
The main cause of the fragile-to-strong crossover of 3D silica was previously attributed to the presence of a low energy cutoff in the potential energy landscape. The important que…
Derivation of a statistical model for classical systems obeying fractional exclusion principle
Projesh Kumar Roy
The violation of the Pauli principle has been surmised in several models of the Fractional Exclusion Statistics and successfully applied to several quantum systems. In this paper,…
Effect of ring stiffness and ambient pressure on the dynamical slowdown in ring polymers
Projesh Kumar Roy, Pinaki Chaudhuri, Satyavani Vemparala
Using extensive molecular dynamics simulations, we investigate the slowing down of dynamics in a 3D system of ring polymers by varying the ambient pressure and the stiffness of the…
Relating local structures, energies, and occurrence probabilities in a two-dimensional silica network
Projesh Kumar Roy, Andreas Heuer
Recently, it became possible to experimentally generate and characterize a very thin silica system on a substrate which can be basically described as a 2D random network. The key s…
Ring statistics in 2D-silica: effective temperatures in equilibrium
Projesh Kumar Roy, Andreas Heuer
The thermodynamic properties of subsystems in strong interaction with the neighborhood can largely differ from the standard behavior. Here we study the thermodynamic properties of…
