Enhanced Phonon Peak in Four-point Dynamic Susceptibility in the Supercooled Active Glass-forming Liquids
Subhodeep Dey, Anoop Mutneja, Smarajit Karmakar
Active glassy systems can be thought of as simple model systems that imitate complex biological systems. Sometimes, it becomes crucial to estimate the amount of the activity presen…
Annealing effects of multidirectional oscillatory shear in model glass formers
Vishnu V. Krishnan, Kabir Ramola, Smarajit Karmakar
We study the effects of cyclic, athermal quasi-static shear on a model glass-forming system in three dimensions. We utilize the three available orthogonal shear planes, namely $XY,…
Non-trivial activity dependence of static length scale and critical tests of active random first-order transition theory
Kallol Paul, Saroj Kumar Nandi, Smarajit Karmakar
Effects of activity on glassy dynamics are fundamental in several biological processes. Active glasses extend the scope of the equilibrium problem and provide new control parameter…
Universal mechanical instabilities in the energy landscape of amorphous solids: evidence from athermal quasistatic expansion
Umang A. Dattani, Smarajit Karmakar, Pinaki Chaudhuri
Using numerical simulations, we study the failure of an amorphous solid under quasi-static expansion starting from a homogeneous high-density state. During the volume expansion, we…
Spatial Dimensionality Dependence of Heterogeneity, Breakdown of the Stokes-Einstein Relation and Fragility of a Model Glass-Forming Liquid
Monoj Adhikari, Smarajit Karmakar, Srikanth Sastry
We investigate the heterogeneity of dynamics, the breakdown of the Stokes-Einstein relation and fragility in a model glass forming liquid, a binary mixture of soft spheres with a h…
Kinetic Fragility Directly Correlates with the Many-body Static Amorphous Order in Glass-Forming Liquids
Indrajit Tah, Smarajit Karmakar
The term "fragility" describes the rate at which viscosity grows when a supercooled liquid approaches its putative glass transition temperature. The field of glassy materials is ac…
