Self-organized hyperuniformity in a minimal model of population dynamics
Tal Agranov, Natan Wiegenfeld, Omer Karin +1
By generalizing a class of models recently introduced to account for protracted transients in biological systems, we identify a novel mechanism for hyperuniformity. In this model,…
Entropy production rate in thermodynamically consistent flocks
Tal Agranov, Robert L. Jack, Michael E. Cates +1
We study the entropy production rate (EPR) of aligning self-propelled particles which undergo a flocking transition towards a polarized collective motion. In our thermodynamically…
Thermodynamically consistent flocking: From discontinuous to continuous transitions
Tal Agranov, Robert L. Jack, Michael E. Cates +1
We introduce a family of lattice-gas models of flocking, whose thermodynamically consistent dynamics admits a proper equilibrium limit at vanishing self-propulsion. These models ar…
Tricritical behavior in dynamical phase transitions
Tal Agranov, Michael E. Cates, Robert L. Jack
We identify a new scenario for dynamical phase transitions associated with time-integrated observables occurring in diffusive systems described by the macroscopic fluctuation theor…
Entropy production and its large deviations in an active lattice gas
Tal Agranov, Michael E. Cates, Robert L. Jack
Active systems are characterized by a continuous production of entropy at steady state. We study the statistics of entropy production within a lattice-based model of interacting ac…
Macroscopic Fluctuation Theory and Current Fluctuations in Active Lattice Gases
Tal Agranov, Sunghan Ro, Yariv Kafri +1
We study the current large deviations for a lattice model of interacting active particles displaying a motility-induced phase separation (MIPS). To do this, we first derive the exa…
Exact fluctuating hydrodynamics of active lattice gases -- Typical fluctuations
Tal Agranov, Sunghan Ro, Yariv Kafri +1
We extend recent results on the exact hydrodynamics of a system of diffusive active particles displaying a motility-induced phase separation to account for typical fluctuations of…
Extinctions of coupled populations, and rare-event dynamics under non-Gaussian noise
Tal Agranov, Guy Bunin
The survival of natural populations may be greatly affected by environmental conditions that vary in space and time. We look at a population residing in two locations (patches) cou…
The Airy distribution: experiment, large deviations and additional statistics
Tal Agranov, Pini Zilber, Naftali R. Smith +3
The Airy distribution (AD) describes the probability distribution of the area under a Brownian excursion. The AD is prominent in several areas of physics, mathematics and computer…
Occupation time statistics of a gas of interacting diffusing particles
Tal Agranov, P. L. Krapivsky, Baruch Meerson
The time which a diffusing particle spends in a certain region of space is known as the occupation time, or the residence time. Recently the joint occupation time statistics of an…
Survival, absorption and escape of interacting diffusing particles
Tal Agranov, Baruch Meerson
At finite concentrations of reacting molecules, kinetics of diffusion-controlled reactions is affected by intra-reactant interactions. As a result, multi-particle reaction statisti…
Narrow escape of interacting diffusing particles
Tal Agranov, Baruch Meerson
The narrow escape problem deals with the calculation of the mean escape time (MET) of a Brownian particle from a bounded domain through a small hole on the domain's boundary. Here…
Fluctuations of absorption of interacting diffusing particles by multiple absorbers
Tal Agranov, Baruch Meerson
We study fluctuations of particle absorption by a three-dimensional domain with multiple absorbing patches. The domain is in contact with a gas of interacting diffusing particles.…
Survival of interacting diffusing particles inside a domain with absorbing boundary
Tal Agranov, Baruch Meerson, Arkady Vilenkin
Suppose that a -dimensional domain is filled with a gas of (in general, interacting) diffusive particles with density . A particle is absorbed whenever it reaches the domai…
