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…
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…
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…
