Role of Fragility of the Glass Formers in the Yielding Transition under Oscillatory Shear
Roni Chatterjee, Monoj Adhikari, Smarajit Karmakar
Amorphous materials, especially metallic glasses, are known for their exceptional mechanical properties, such as high yield strength and large yield strain. Understanding the micro…
Study of flow of crystals and deformable particles in a channel and the effective segregation of soft and hard particles
Padmanabha Bose, Smarajit Karmakar
Soft matters whose constituents are deformable are ubiquitous in nature especially in biological systems-including cells and their organelles-as well as in foams and emulsions. The…
Anomalous Dynamical Heterogeneity in Active Glasses as a Signature of Violation of Mermin-Wagner-Hohenberg Theorem
Subhodeep Dey, Smarajit Karmakar
Two-dimensional (2D) systems have attracted renewed interest within the scientific community due to their anomalous dynamical behaviors, which arise from long-wavelength density fl…
Enhanced Long Wavelength Mermin-Wagner Fluctuations in Active Crystals and Glasses
Subhodeep Dey, Antik Bhattacharya, Smarajit Karmakar
In two-dimensions (2D), the Mermin-Wagner-Hohenberg (MWH) fluctuation plays a significant role, giving rise to striking dimensionality effects marked by long-range density fluctuat…
Inverse Bauschinger to Bauschinger Crossover under Steady Shear in Amorphous Solids
Rashmi Priya, Smarajit Karmakar
Directional memory in amorphous solids is commonly quantified through the Bauschinger effect, yet the observation of the inverse Bauschinger effect suggests that the sign of memory…
Growth of Dynamic and Static Correlations in the Aging Dynamics of a Glass-Forming Liquid
Santu Nath, Smarajit Karmakar
Using extensive molecular dynamics simulations, we have performed finite-size scaling (FSS) in the aging regime of a model glass-forming liquid to investigate how the length scales…
