Response of a hexagonal granular packing under a localized overload: effects of pressure
S. Ostojic, D. Panja
We study the response of a two-dimensional hexagonal packing of rigid, frictionless spherical grains due to a vertically downward point force on a single grain at the top layer. We…
Response of a Hexagonal Granular Packing under a Localized External Force: Exact Results
Srdjan Ostojic, Debabrata Panja
We study the response of a two-dimensional hexagonal packing of massless, rigid, frictionless spherical grains due to a vertically downward point force on a single grain at the top…
Fluctuating Fronts as Correlated Extreme Value Problems: An Example of Gaussian Statistics
Debabrata Panja
In this paper, we view fluctuating fronts made of particles on a one-dimensional lattice as an extreme value problem. The idea is to denote the configuration for a single front rea…
Asymptotic Scaling of the Diffusion Coefficient of Fluctuating "Pulled" Fronts
Debabrata Panja
We present a (heuristic) theoretical derivation for the scaling of the diffusion coefficient for fluctuating ``pulled'' fronts. In agreement with earlier numerical simulation…
Long-time-tail Effects on Lyapunov Exponents of a Random, Two-dimensional Field-driven Lorentz Gas
D. Panja, J. R. Dorfman, Henk van Beijeren
We study the Lyapunov exponents for a moving, charged particle in a two-dimensional Lorentz gas with randomly placed, non-overlapping hard disk scatterers placed in a thermostatted…
