Persistently Non-Gaussian Metastable Liquids
Vinay Vaibhav, Tamoghna Das, Suman Dutta
Particles undergoing Fickian diffusion within smooth energy landscapes exhibit Gaussian statistics. However, this Gaussian behavior is often elusive in complex liquids, where parti…
Activity-driven sorting, approach to criticality and turbulent flows in dense persistent active fluids
Suman Dutta, Pinaki Chaudhuri, Madan Rao +1
We show that dense active fluids comprising interacting particles with persistent self-propulsion are driven to a non-equilibrium steady state consisting of co-moving particles wit…
Entropic Timescales of Dynamic Heterogeneity in Supercooled Liquid
Vinay Vaibhav, Suman Dutta
Non-Gaussian displacement distributions are universal predictors of dynamic heterogeneity in slowly varying environments. Here, we explore heterogeneous dynamics in supercooled liq…
Creep response of athermal amorphous solids under imposed shear stress
Suman Dutta, Kirsten Martens, Pinaki Chaudhuri
Yield stress materials fail when the imposed stress crosses a critical threshold. A well-known dynamical response to the applied stress is the phenomenon of creep where the cumulat…
Length-scales of Dynamic Heterogeneity in a Driven Binary Colloid
S. Dutta, J. Chakrabarti
Here we study characteristic length scales in an aqueous suspension of symmetric oppositely charged colloid subject to a uniform electric field by Brownian Dynamics simulations. We…
Non Gaussian information of heterogeneity in Soft Matter
Rahul Dandekar, Soumyakanti Bose, Suman Dutta
Heterogeneity in dynamics in the form of non-Gaussian molecular displacement distributions appears ubiquitously in soft matter. We address the quantification of such heterogeneity…
Microscopic Insights into Dynamical Heterogeneity in a Lane-forming Liquid
Suman Dutta
Dynamical heterogeneity (DH) in non-equilibrium systems is a topic of profound interest yet an open question. In a model system of constantly driven oppositely charged binary collo…
Heterogeneous Dynamical Relaxations in a Lane Forming Liquid
Suman Dutta
The connection between domain relaxations at individual scales and the collective heterogeneous response in non-equilibrium systems is a topic of profound interest in recent times.…
Anomalous Dynamical Responses in a Driven System
Suman Dutta, J. Chakrabarti
The interplay between structure and dynamics in non-equilibrium steady-state is far from understood. We address this interplay by tracking Brownian Dynamics trajectories of particl…
Analytical Form of Forces in Hydrophobic Collapse
J. Chakrabarti, Suman Dutta
We calculate analytically the forces between two solvophobic solutes, considering a model system. We show that the effective interaction forces between two solvophobic solutes, med…
