Persistence in nonequilibrium surface growth
M. Constantin, C. Dasgupta, P. Punyindu Chatraphorn +2
Persistence probabilities of the interface height in (1+1)- and (2+1)-dimensional atomistic, solid-on-solid, stochastic models of surface growth are studied using kinetic Monte Car…
Survival in equilibrium step fluctuations
C. Dasgupta, M. Constantin, S. Das Sarma +1
We report the results of analytic and numerical investigations of the time scale of survival or non-zero-crossing probability in equilibrium step fluctuations described by L…
Mean-field Monte Carlo Approach to the Dynamics of a One Pattern Model of Associative Memory
Manoranjan P. Singh, Chandan Dasgupta
We have used a mean-field Monte Carlo method to study the zero-temperature synchronous dynamics of a one-pattern model of associative memory with random asymmetric couplings. In th…
Infinite family of persistence exponents for interface fluctuations
M. Constantin, S. Das Sarma, C. Dasgupta +3
We show experimentally and theoretically that the persistence of large deviations in equilibrium step fluctuations is characterized by an infinite family of independent exponents.…
Mound formation and coarsening from a nonlinear instability in surface growth
Buddhapriya Chakrabarti, Chandan Dasgupta
We study a class of one-dimensional, nonequilibrium, conserved growth equations for both nonconserved and conserved noise statistics using numerical integration. An atomistic versi…
Free energy landscape in a dense hard sphere system
Chandan Dasgupta, Oriol T. Valls
The topography of the free energy landscape in phase space of a dense hard sphere system characterized by a discretized free energy functional of the Ramakrishnan-Yussouff form is…
