Spatiotemporal rheochaos in nematic hydrodynamics
Buddhapriya Chakrabarti, Moumita Das, Chandan Dasgupta +2
Motivated by the observation of rheochaos in sheared wormlike micelles [Bandyopadhyay et al., Phys. Rev. Lett, 84 2022, (2000); Europhys. Lett. 56, 447 (2001); Pramana 53, 223 (199…
Spatial persistence and survival probabilities for fluctuating interfaces
M. Constantin, S. Das Sarma, C. Dasgupta
We report the results of numerical investigations of the steady-state (SS) and finite-initial-conditions (FIC) spatial persistence and survival probabilities for (1+1)--dimensional…
Two-step melting of the vortex solid in layered superconductors with random columnar pins
Chandan Dasgupta, Oriol T. Valls
We consider the melting of the vortex solid in highly anisotropic layered superconductors with a small concentration of random columnar pinning centers. Using large-scale numerical…
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.…
