Multifractional Brownian motion with telegraphic, stochastically varying exponent
Michał Balcerek, Samudrajit Thapa, Krzysztof Burnecki +4
The diversity of diffusive systems exhibiting long-range correlations characterized by a stochastically varying Hurst exponent calls for a generic multifractional model. We present…
Optimal conditions for first passage of jump processes with resetting
Mattia Radice, Giampaolo Cristadoro, Samudrajit Thapa
We investigate the first passage time beyond a barrier located at of a random walk with independent and identically distributed jumps, starting from . The walk is s…
Nonequilibrium Probability Currents in Optically-Driven Colloidal Suspensions
Samudrajit Thapa, Daniel Zaretzky, Ron Vatash +4
In the absence of directional motion it is often hard to recognize athermal fluctuations. Probability currents provide such a measure in terms of the rate at which they enclose are…
Emergent clustering due to quorum sensing interactions in active matter
Samudrajit Thapa, Bat-El Pinchasik, Yair Shokef
Many organisms in nature use local interactions to generate global cooperative phenomena. To unravel how the behavior of individuals generates effective interactions within a group…
Fractional Brownian motion with random Hurst exponent: accelerating diffusion and persistence transitions
Michał Balcerek, Krzysztof Burnecki, Samudrajit Thapa +2
Fractional Brownian motion, a Gaussian non-Markovian self-similar process with stationary long-correlated increments, has been identified to give rise to the anomalous diffusion be…
Bayesian inference of scaled versus fractional Brownian motion
Samudrajit Thapa, Seongyu Park, Yeongjin Kim +3
We present a Bayesian inference scheme for scaled Brownian motion, and investigate its performance on synthetic data for parameter estimation and model selection in a combined infe…
Bayesian inference of Lévy walks via hidden Markov models
Seongyu Park, Samudrajit Thapa, Yeongjin Kim +2
The Lévy walk is a non-Brownian random walk model that has been found to describe anomalous dynamic phenomena in diverse fields ranging from biology over quantum physics to ecology…
Objective comparison of methods to decode anomalous diffusion
Gorka Muñoz-Gil, Giovanni Volpe, Miguel Angel Garcia-March +31
Deviations from Brownian motion leading to anomalous diffusion are found in transport dynamics from quantum physics to life sciences. The characterization of anomalous diffusion fr…
Leveraging large-deviation statistics to decipher the stochastic properties of measured trajectories
Samudrajit Thapa, Agnieszka Wyłomańska, Grzegorz Sikora +5
Extensive time-series encoding the position of particles such as viruses, vesicles, or individual proteins are routinely garnered in single-particle tracking experiments or superco…
