Activity-Induced Structural and Dynamical Heterogeneity in Colloidal Gels
Santu Nath, Sudipta Mandal, Smarajit Karmakar
Active gels are intrinsically non-equilibrium materials whose structural and dynamical heterogeneity emerges from the interplay of attractive interactions, thermal fluctuations, an…
Enhanced Long-Wavelength Fluctuations and Interaction-Stress Correlations in Active Crystals
Antik Bhattacharya, Smarajit Karmakar
Activity can enhance the long-wavelength density fluctuations of a solid beyond the equilibrium fluctuations predicted by the Mermin-Wagner-Hohenberg theorem, but the microscopic o…
The Universal Role of Fragility on the Yielding Transition of Active Glass under Oscillatory Shear
Arnab Mandal, Roni Chatterjee, Smarajit Karmakar
The yielding transition marks the onset of irreversible plastic deformation in amorphous solids and plays a central role in determining the mechanical stability and failure of meta…
Active Brownian Dynamics from a Hamiltonian Model: Transitioning from Equilibrium to Activity
Antik Bhattacharya, Smarajit Karmakar, Jürgen Horbach
We introduce a Hamiltonian Active Brownian Particle (HABP) model that connects equilibrium dynamics with the non-equilibrium, two-dimensional overdamped behavior of standard Active…
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…
