Spatial density, first passage times, and entropy of run and tumble particles in a bistable potential
R. K. Singh, Erez Aghion
We study the dynamics of a run and tumble particle (RTP) in a bistable potential, in contact with a heat bath. We find the exact form of the steady state position distribution as w…
Harvesting Reshapes Dynamical Populations
R. K. Singh, Michael Assaf, Jason R. Green +1
Harvesting -- the periodic removal of individuals above or below a threshold trait value -- reshapes heterogeneous populations without altering their underlying stochastic dynamics…
Force Geometry and Irreversibility in Nonequilibrium Overdamped Dynamics
Erez Aghion, Swetamber Das
Recent experiments have revealed heterogeneous dissipation in optically trapped systems, often anticorrelated with local positional fluctuations, exposing a structural gap in the s…
Quantifying Coupled Dynamics in Phase-Space from State Distribution Snapshots
Erez Aghion, Nava Leibovich
We quantify nonlinear interactions between coupled complex processes, when the system is subject to noise and not all its components are measurable. Our method is applicable even w…
Local equilibrium properties of ultraslow diffusion in the Sinai model
Amin Padash, Erez Aghion, Alexander Schulz +4
We perform numerical studies of a thermally driven, overdamped particle in a random quenched force field, known as the Sinai model. We compare the unbounded motion on an infinite 1…
Classification of anomalous diffusion in animal movement data using power spectral analysis
Ohad Vilk, Erez Aghion, Ran Nathan +3
The field of movement ecology has seen a rapid increase in high-resolution data in recent years, leading to the development of numerous statistical and numerical methods to analyse…
Thermodynamic speed limits for mechanical work
Erez Aghion, Jason R. Green
Thermodynamic speed limits are a set of classical uncertainty relations that, so far, place global bounds on the stochastic dissipation of energy as heat and the production of entr…
Unravelling the origins of anomalous diffusion: from molecules to migrating storks
Ohad Vilk, Erez Aghion, Tal Avgar +10
Anomalous diffusion or, more generally, anomalous transport, with nonlinear dependence of the mean-squared displacement on the measurement time, is ubiquitous in nature. It has bee…
Anomalous diffusion in the citation time series of scientific publications
Maryam Zamani, Erez Aghion, Peter Pollner +2
We analyze the citation time-series of manuscripts in three different fields of science; physics, social science and technology. The evolution of the time-series of the yearly numb…
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…
Moses, Noah and Joseph Effects in Coupled Lévy Processes
Erez Aghion, Philipp G. Meyer, Vidushi Adalkha +2
We study a method for detecting the origins of anomalous diffusion, when it is observed in an ensemble of times-series, generated experimentally or numerically, without having know…
Infinite ergodic theory meets Boltzmann statistics
Erez Aghion, David A. Kessler, Eli Barkai
We investigate the overdamped stochastic dynamics of a particle in an asymptotically flat external potential field, in contact with a thermal bath. For an infinite system size, the…
From Non-normalizable Boltzmann-Gibbs statistics to infinite-ergodic theory
Erez Aghion, David A. Kessler, Eli Barkai
We study a particle immersed in a heat bath, in the presence of an external force which decays at least as rapidly as , for example a particle interacting with a surface throu…
Large-deviations for spatial diffusion of cold atoms
Erez Aghion, David A. Kessler, Eli Barkai
Large-deviations theory deals with tails of probability distributions and the rare events of random processes, for example spreading packets of particles. Mathematically, it concer…
Fluctuations of ring polymers
Shlomi Medalion, Erez Aghion, Hagai Meirovitch +2
We present an exact solution for the distribution of sample averaged monomer to monomer distance of ring polymers. For non-interacting and weakly-interacting models these distribut…
From the area under the Bessel excursion to anomalous diffusion of cold atoms
E. Barkai, E. Aghion, D. A. Kessler
Levy flights are random walks in which the probability distribution of the step sizes is fat-tailed. Levy spatial diffusion has been observed for a collection of ultra-cold Rb atom…
