Classification, inference and segmentation of anomalous diffusion with recurrent neural networks
Aykut Argun, Giovanni Volpe, Stefano Bo
Countless systems in biology, physics, and finance undergo diffusive dynamics. Many of these systems, including biomolecules inside cells, active matter systems and foraging animal…
Functionals in stochastic thermodynamics: how to interpret stochastic integrals
Stefano Bo, Soon Hoe Lim, Ralf Eichhorn
In stochastic thermodynamics standard concepts from macroscopic thermodynamics, such as heat, work, and entropy production, are generalized to small fluctuating systems by defining…
Measurement of Anomalous Diffusion Using Recurrent Neural Networks
Stefano Bo, Falko Schmidt, Ralf Eichhorn +1
Anomalous diffusion occurs in many physical and biological phenomena, when the growth of the mean squared displacement (MSD) with time has an exponent different from one. We show t…
Irreversibility in active matter systems: Fluctuation theorem and mutual information
Lennart Dabelow, Stefano Bo, Ralf Eichhorn
We consider a Brownian particle which, in addition to being in contact with a thermal bath, is driven by fluctuating forces which stem from active processes in the system, such as…
Experimental Realization of a Minimal Microscopic Heat Engine
Aykut Argun, Jalpa Soni, Lennart Dabelow +4
Microscopic heat engines are microscale systems that convert energy flows between heat reservoirs into work or systematic motion. We have experimentally realized a minimal microsco…
Driven anisotropic diffusion at boundaries: noise rectification and particle sorting
Stefano Bo, Ralf Eichhorn
We study the diffusive dynamics of a Brownian particle in proximity of a flat surface under non-equilibrium conditions, which are created by an anisotropic thermal environment with…
Steady diffusion in a drift field: a comparison of large deviation techniques and multiple-scale analysis
Erik Aurell, Stefano Bo
A particle with internal unobserved states diffusing in a force field will generally display effective advection-diffusion. The drift velocity is proportional to the mobility avera…
Multiple-scale stochastic processes: decimation, averaging and beyond
Stefano Bo, Antonio Celani
The recent experimental progresses in handling microscopic systems have allowed to probe them at levels where fluctuations are prominent, calling for stochastic modeling in a large…
Diffusion of a Brownian ellipsoid in a force field
Erik Aurell, Stefano Bo, Marcelo Dias +2
We calculate the effective long-term convective velocity and dispersive motion of an ellipsoidal Brownian particle in three dimensions when it is subjected to a constant external f…
Optimal stochastic transport in inhomogeneous thermal environments
Stefano Bo, Erik Aurell, Ralf Eichhorn +1
We consider optimization of the average entropy production in inhomogeneous temperature environments within the framework of stochastic thermodynamics. For systems modeled by Lange…
Entropic anomaly and maximal efficiency of microscopic heat engines
Stefano Bo, Antonio Celani
The efficiency of microscopic heat engines in a thermally heterogenous environment is considered. We show that, as a consequence of the recently discovered entropic anomaly, quasi-…
Anomalous thermodynamics at the micro-scale
Antonio Celani, Stefano Bo, Ralf Eichhorn +1
Particle motion at the micro-scale is an incessant tug-of-war between thermal fluctuations and applied forces on one side, and the strong resistance exerted by fluid viscosity on t…
