Persistence and survival in equilibrium step fluctuations
M. Constantin, C. Dasgupta, S. Das Sarma +2
Results of analytic and numerical investigations of first-passage properties of equilibrium fluctuations of monatomic steps on a vicinal surface are reviewed. Both temporal and spa…
Sampling Time Effects for Persistence and Survival in Step Structural Fluctuations
D. B. Dougherty, C. Tao, O. Bondarchuk +5
The effects of sampling rate and total measurement time have been determined for single-point measurements of step fluctuations within the context of first-passage properties. Time…
Experimental Persistence Probability for Fluctuating Steps
D. B. Dougherty, I. Lyubinetsky, E. D. Williams +3
The persistence behavior for fluctuating steps on the surface was determined by analyzing time-dependent STM images for temperatures…
Neural Network Model for Apparent Deterministic Chaos in Spontaneously Bursting Hippocampal Slices
B. Biswal, C. Dasgupta
A neural network model that exhibits stochastic population bursting is studied by simulation. First return maps of inter-burst intervals exhibit recurrent unstable periodic orbit (…
Instability, Intermittency and Multiscaling in Discrete Growth Models of Kinetic Roughening
C. Dasgupta, J. M. Kim, M. Dutta +1
We show by numerical simulations that discretized versions of commonly studied continuum nonlinear growth equations (such as the Kardar-Parisi-Zhang equation and the Lai-Das Sarma…
