Heterogeneous attenuation of sound waves in three-dimensional amorphous solids
Shivam Mahajan, Massimo Pica Ciamarra
Sound waves are attenuated as they propagate in amorphous materials. We investigate the mechanism driving sound attenuation in the Rayleigh scattering regime by resolving the dynam…
Designing Phononic Band Gaps with Sticky Potentials
Yuanjian Zheng, Shivam Mahajan, Joyjit Chattoraj +1
Spectral gaps in the vibrational modes of disordered solids are key design elements in the synthesis and control of phononic metamaterials that exhibit a plethora of novel elastic…
In-silico modeling of early-stage biofilm formation
Pin Nie, Francisco Alarcon Oseguera, Ivan Lopez-Montero +3
Several bacteria and bacteria strands form biofilms in different environmental conditions, e.g. pH, temperature, nutrients, etc. Biofilm growth, therefore, is an extremely robust p…
Reverse Janssen effect in narrow granular columns
Shivam Mahajan, Michael Tennenbaum, Sudhir N. Pathak +6
When grains are added to a cylinder, the weight at the bottom is smaller than the total weight of the column, which is partially supported by the lateral walls through wall/grain f…
Long-wavelength fluctuations and anomalous dynamics in two-dimensional liquids
Yanwei Li, Chandan K. Mishra, Zhaoyan Sun +4
Long-wavelength Mermin-Wagner fluctuations prevent the existence of translational long-range order, in two-dimensional systems at finite temperature. Their dynamical signature, whi…
Oscillatory Instabilities in Frictional Granular Matter
Joyjit Chattoraj, Oleg Gendelman, Massimo Pica Ciamarra +1
Frictional granular matter is shown to be fundamentally different in its plastic responses to external strains from generic glasses and amorphous solids without friction. While reg…
