Optimizing search processes in systems with state toggling: exact condition delimiting the efficacy of stochastic resetting strategy
Hillol kumar Barman, Amitabha Nandi, Dibyendu Das
Will the strategy of resetting} help a stochastic process to reach its target efficiently, with its environment continually toggling between a strongly favourable and an unfavourab…
Comparing the roles of time overhead and spatial dimensions on optimal resetting rate vanishing transitions, in Brownian processes with potential bias and stochastic resetting
Saeed Ahmad, Dibyendu Das
The strategy of stochastic resetting is known to expedite the first passage to a target, in diffusive systems. Consequently, the mean first passage time is minimized at an optimal…
Sufficient conditions for the additivity of stall forces generated by multiple filaments or motors
Tripti Bameta, Dipjyoti Das, Dibyendu Das +2
Molecular motors and cytoskeletal filaments work collectively most of the time under opposing forces. This opposing force may be due to cargo carried by motors or resistance coming…
Force-induced dynamical properties of multiple cytoskeletal filaments are distinct from that of single filaments
Dipjyoti Das, Dibyendu Das, Ranjith Padinhateeri
How cytoskeletal filaments collectively undergo growth and shrinkage is an intriguing question. Collective properties of multiple bio-filaments (actin or microtubules) undergoing h…
Collective force generated by multiple biofilaments can exceed the sum of forces due to individual ones
Dipjyoti Das, Dibyendu Das, Ranjith Padinhateeri
Collective dynamics and force generation by cytoskeletal filaments are crucial in many cellular processes. Investigating growth dynamics of a bundle of N independent cytoskeletal f…
Giant number fluctuations in microbial ecologies
Dipjyoti Das, Dibyendu Das, Ashok Prasad
Statistical fluctuations in population sizes of microbes may be quite large depending on the nature of their underlying stochastic dynamics. For example, the variance of the popula…
Dynamics of a flexible polymer in planar mixed flow
Dipjyoti Das, Sanjib Sabhapandit, Dibyendu Das
We present exact spatio-temporal correlation functions of a Rouse polymer chain submerged in a fluid having planar mixed flow, in the steady state. Using these correlators, determi…
Particles Sliding on a Fluctuating Surface: Phase Separation and Power Laws
Dibyendu Das, Mustansir Barma
We study a system of hard-core particles sliding downwards on a fluctuating one-dimensional surface which is characterized by a dynamical exponent . In numerical simulations, an…
