Jamming states in random sequential adsorption of diffusion-limited aggregates
Fahad Puthalath, Dipanjan Mandal, Sumanta Kundu
Motivated by the ubiquity of ramified fractal deposits in nature and engineered systems, we investigate the irreversible adsorption of diffusion-limited aggregation (DLA) clusters…
U-Net based particle localization in granular experiments: Accuracy limits and optimization
Fahad Puthalath, Matthias Schröter, Nicoletta Sanvitale +2
Identifying the positions of granular particles from experimental images is often complicated by their partial overlap in two dimensional projections. Uneven backgrounds and inhomo…
Towards probing velocity distributions in dense granular matter: Utilizing Fiber Bragg Gratings
Marlo Kunzner, Luis Henriques, Fahad Puthalath +8
Granular gases are commonly characterized through their velocity distribution, which provides access to the granular temperature. In experiments, velocity distributions are typical…
Lattice models for ballistic aggregation: cluster-shape dependent exponents
Fahad Puthalath, Apurba Biswas, V. V. Prasad +1
We study ballistic aggregation on a two dimensional square lattice, where particles move ballistically in between momentum and mass conserving coalescing collisions. Three models a…
