Close-packed granular clusters: hydrostatics and persistent Gaussian fluctuations
Baruch Meerson, Manuel Diez-Minguito, Thomas Schwager +1
Dense granular clusters often behave like macro-particles. We address this interesting phenomenon in a model system of inelastically colliding hard disks inside a circular box, dri…
Spectral theory of metastability and extinction in birth-death systems
Michael Assaf, Baruch Meerson
We suggest a general spectral method for calculating statistics of multi-step birth-death processes and chemical reactions of the type mA->nA (m and n are positive integers) which…
Spectral formulation and WKB approximation for rare-event statistics in reaction systems
Michael Assaf, Baruch Meerson
We develop a spectral formulation and a stationary WKB approximation for calculating the probabilities of rare events (large deviations from the mean) in systems of reacting partic…
The role of discrete-particle noise in the Ostwald ripening
Baruch Meerson, Leonard M. Sander, Peter Smereka
We investigate the role of discrete-particle noise in interface-controlled Ostwald ripening. We introduce the noise within the framework of the Becker-Doering equations, and employ…
Hydrodynamic singularities and clustering in a freely cooling inelastic gas
Efi Efrati, Eli Livne, Baruch Meerson
We employ hydrodynamic equations to follow the clustering instability of a freely cooling dilute gas of inelastically colliding spheres into a well-developed nonlinear regime. We s…
