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…
Interaction of multiple spiral rotors in a reaction-diffusion system
Hrishikesh Kalita, Sumana Dutta
Rotors of reaction and diffusion, that revolve around a circular singularity, and the corresponding spiral wave activity around it, influence the nature of several excitable media.…
Following Forrelation -- Quantum Algorithms in Exploring Boolean Functions' Spectra
Suman Dutta, Subhamoy Maitra, Chandra Sekhar Mukherjee
Here we revisit the quantum algorithms for obtaining Forrelation [Aaronson et al, 2015] values to evaluate some of the well-known cryptographically significant spectra of Boolean f…
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…
Dynamics of Interacting Hotspots -- I
Suman Dutta
The worldwide spread of COVID-19 has called for fast advancement of new modelling strategies to estimate its unprecedented spread. Here, we introduce a model based on the fundament…
Dynamics of Interacting Hotspots - II
Suman Dutta
In the absence of any proper clinical solution, human civilization is only left with sophisticated intervention measures to contain the spread of COVID-19. However, the existing mo…
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…
