Stress Response of Jammed Solids: Prestress and Screening
Surajit Chakraborty, Jishnu N. Nampoothiri, Subhro Bhattacharjee +2
Unlike classical elasticity, where stresses arise from deformations relative to a stress-free reference configuration, rigidity in amorphous systems is maintained by disordered for…

Instabilities govern the low-frequency vibrational spectrum of amorphous solids
Surajit Chakraborty, Roshan Maharana, Smarajit Karmakar +1
Amorphous solids exhibit an excess of low-frequency vibrational modes beyond the Debye prediction, contributing to their anomalous mechanical and thermal properties. Although a $Ï…

Long-Range Correlations in Elastic Moduli and Local Stresses at the Unjamming Transition
Surajit Chakraborty, Kabir Ramola
We explore the behavior of spatially heterogeneous elastic moduli as well as the correlations between local moduli in model solids with short-range repulsive potentials. We show th…
