Resolution dependence of most probable pathways with state-dependent diffusivity
Alice L. Thorneywork, Jannes Gladrow, Ulrich F. Keyser +3
Recent experiments have probed the relative likelihoods of trajectories in stochastic systems by observing survival probabilities within a tube of radius in spacetime. We measu…
Experimental measurement of relative path probabilities and stochastic actions
Jannes Gladrow, Ulrich F. Keyser, R. Adhikari +1
For diffusive stochastic dynamics, the probability to observe any individual trajectory is vanishingly small, making it unclear how to experimentally validate theoretical results f…
Ritz method for transition paths and quasipotentials of rare diffusive events
Lukas Kikuchi, Rajesh Singh, Mike E. Cates +1
The probability of trajectories of weakly diffusive processes to remain in the tubular neighbourhood of a smooth path is given by the Freidlin-Wentzell-Graham theory of large devia…
Lattice Boltzmann - Langevin simulations of binary mixtures
P. T. Sumesh, Ignacio Pagonabarraga, Ronojoy Adhikari
We report a hybrid numerical method for the solution of the model H fluctuating hydrodynamic equations for binary mixtures. The momentum conservation equations with Landau-Lifshitz…
Endogenous Quasicycles and Stochastic Coherence in a Closed Endemic Model
Somdeb Ghose, R. Adhikari
We study the role of demographic fluctuations in typical endemics as exemplified by the stochastic SIRS model. The birth-death master equation of the model is simulated using exact…
Run-and-tumble particles with hydrodynamics: sedimentation, trapping and upstream swimming
R. W. Nash, R. Adhikari, J. Tailleur +1
We simulate by lattice Boltzmann the nonequilibrium steady states of run-and-tumble particles (inspired by a minimal model of bacteria), interacting by far-field hydrodynamics, sub…
Non-Markovian fluctuations in Markovian models of protein dynamics
Arti Dua, R. Adhikari
Recent experiments using fluorescence spectroscopy have been able to probe the dynamics of conformational fluctuations in proteins. The fluctuations are Gaussian but do not decay e…
