Interplay of instabilities in mounded surface growth
Buddhapriya Chakrabarti, Chandan Dasgupta
We numerically study a one-dimensional conserved growth equation with competing linear (Ehrlich-Schwoebel) and nonlinear instabilities. As a control parameter is varied, this model…
Correlation Time for Step Structural Fluctuations
O. Bondarchuk, D. B. Dougherty, M. Degawa +4
Time dependent STM has been used to evaluate step fluctuations as a function of temperature (300-450 K) on Ag(111) films grown on mica. The temporal correlation function scales as…
Routes to spatiotemporal chaos in the rheology of nematogenic fluids
Moumita Das, Buddhapriya Chakrabarti, Chandan Dasgupta +2
With a view to understanding the ``rheochaos'' observed in recent experiments in a variety of orientable fluids, we study numerically the equations of motion of the spatiotemporal…
Melting and structure of the vortex solid in strongly anisotropic layered superconductors with random columnar pins
Chandan Dasgupta, Oriol T. Valls
We study the melting transition of the low-temperature vortex solid in strongly anisotropic layered superconductors with a concentration of random columnar pinning centers small en…
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…
