Mode-coupling theory for aging in active glasses: relaxation dynamics and evolution towards steady state
Soumitra Kolya, Nir S. Gov, Saroj Kumar Nandi
Aging refers to the evolution of system properties with waiting time . It is a key feature of glassy dynamics. Recent experiments have demonstrated aging in biological systems…
Resetting dynamics in a system with quenched disorder
Riya Verma, Binayak Banerjee, Shamik Gupta +1
Although resetting has widespread applicability, applying it to the dynamics in the presence of spatial quenched disorder, which is essential in many physical problems, is challeng…
A constitutive model for discontinuous shear thickening in epithelial tissues
Tanmoy Ghosh, Kabir Ramola, Saroj Kumar Nandi
The rheological properties of biological tissues, though fundamental to many physiological and pathological processes such as embryonic development, wound healing, and tumor progre…
Scaling the glassy dynamics of active particles: Tunable fragility and reentrance
Puneet Pareek, Peter Sollich, Saroj Kumar Nandi +1
Understanding the influence of activity on dense amorphous assemblies is crucial for biological processes such as wound healing, embryogenesis, or cancer progression. Here, we stud…
An elastoplastic model approach for the relaxation dynamics of active glasses
Tanmoy Ghosh, Peter Sollich, Saroj Kumar Nandi
How activity affects the glassy dynamics is crucial for several biological processes. Furthermore, active glasses offer fascinating phenomenologies, extend the scope of equilibrium…
Active Inhomogeneous Mode-Coupling Theory (aIMCT) for Dense Systems of Self-Propelled Particles
Soumitra Kolya, Puneet Pareek, Saroj Kumar Nandi
Glassy dynamics in a dense system of active particles with self-propulsion force and persistence time are crucial for many biological processes. Recent studies have sho…
