Intruder Dynamics in a Frictional Granular Fluid: A Molecular Dynamics Study
Prasenjit Das, Sanjay Puri, Moshe Schwartz
We study the dynamics of an intruder moving through a fluidized granular medium in three dimensions (). The intruder and grains have both translational and rotational degrees…
Universal Density of Low Frequency States in Amorphous Solids at Finite Temperatures
Prasenjit Das, Itamar Procaccia
It has been established that the low frequency quasi-localized modes of amorphous solids at zero temperature exhibit universal density of states, depending on the frequencies as $D…
Surface-directed Spinodal Decomposition on Morphologically Patterned Substrates
Prasenjit Das, Prabhat K. Jaiswal, Sanjay Puri
This paper is the second in a two-part exposition on {\it surface-directed spinodal decomposition} (SDSD), i.e., the interplay of kinetics of wetting and phase separation at a surf…
Robustness of Density of Low Frequency States in Amorphous Solids
Prasenjit Das, H. George E. Hentschel, Edan Lerner +1
Low frequency quasi-localized modes of amorphous glasses appear to exhibit universal density of states, depending on the frequencies as . To date various models of g…
Surface-Directed Spinodal Decomposition on Chemically Patterned Substrates
Prasenjit Das, Prabhat K. Jaiswal, Sanjay Puri
{\it Surface-directed spinodal decomposition} (SDSD) is the kinetic interplay of phase separation and wetting at a surface. This process is of great scientific and technological im…
Plastic Instabilities in Charged Granular Systems: Competition between Elasticity and Electrostatics
Prasenjit Das, H. George E. Hentschel, Itamar Procaccia
Electrostatic theory preserves charges, but allows dipolar excitations. Elasticity theory preserves dipoles, but allows quadrupolar (Eshelby like) plastic events. Charged amorphous…
