Effect of Temperature on the Complexity of Solid Argon System
A Giri, S Dey, P Barat
We study the measure of complexity in solid Argon system from the time series data of kinetic energy of single Argon atoms at different equilibrated temperatures. To account the in…
Modality of Equilibration in Non-equilibrium Systems
P. Barat, A. Giri, Nilangshu K. Das +2
An open question in the field of non-equilibrium statistical physics is whether there exists a unique way through which non-equilibrium systems equilibrate irrespective of how far…
Oscillatory Shannon Entropy in the Process of Equilibration of Nonequilibrium Systems
A. Giri, Nilangshu K. Das, P. Barat
We present a study of the equilibration process of nonequilibrium systems by means of molecular dynamics simulation technique. The nonequilibrium conditions are achieved in systems…
Statistics of dislocation pinning at localized obstacles
A. Dutta, M. Bhattacharya, P. Barat
Pinning of dislocations at nanosized obstacles like precipitates, voids and bubbles, is a crucial mechanism in the context of phenomena like hardening and creep. The interaction be…
Universal Scaling Property of System Approaching Equilibrium
P. Barat, A. Giri, M. Bhattacharya +2
In this Letter we show that the diffusion kinetics of kinetic energy among the atoms in non- equilibrium crystalline systems follows universal scaling relation and obey Levy-walk p…
Quasistatic Stick-slip in Dislocation Core and Frenkel-Kontorova Chain
M. Bhattacharya, A. Dutta, P. Barat
By means of atomistic simulations, we demonstrate that a dislocation core exhibits intermittent quasistatic restructuring during incremental shear within the same Peierls valley. T…
