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…
What do the fast dynamics tell us about aggregation?
Tamoghna Das
Two typical morphology of two-dimensional aggregates are considered: compact crystalline clusters and string-like non-compact conformations. Simulated trajectories of both types of…
Quantifying `local softness' in a simple liquid
Tamoghna Das
Mutual information between local stress and local non-affine deformation is proposed as a collective field variable quantifying the {\em local softness} of soft materials. The liqu…
Collective dynamics in two-dimensional aggregations with competing interactions
Tamoghna Das, M. M. Bandi
A generic aggregate forming system in two dimensions (2D) is studied using canonical ensemble constant temperature molecular dynamics simulation. The aggregates form due to the com…
Three-state structural heterogeneity in a model two dimensional fluid
Tamoghna Das, Jack F. Douglas
Three structural populations with distinct average mobility are identified within an equilibrium two-dimensional Lennard-Jones fluid simulated via molecular dynamics at a constant…
Quantifying Structural Dynamic Heterogeneity in a Dense Two-dimensional Equilibrium Liquid
Tamoghna Das, Jack F. Douglas
We investigate the local structural fluctuations of a model equilibrium fluid with an aim of better understanding the structural basis of locally heterogeneous dynamics identified…
Transition in heterogeneous dynamics across the morphological hierarchy in two-dimensional aggregates
Tamoghna Das, T. Lookman, M. M. Bandi
Two-dimensional (2D) particulate aggregates formed due to competing interactions exhibit a range of non-equilibrium steady state morphologies from finite-size compact crystalline s…
A Minimal description of morphological hierarchy in two-dimensional aggregates
Tamoghna Das, T. Lookman, M. M. Bandi
A dimensionless parameter is proposed to describe a hierarchy of morphologies in two-dimensional (2D) aggregates formed due to varying competition between short-range attractio…
Structural Transitions in A Crystalline Bilayer : The Case of Lennard Jones and Gaussian Core Models
Tamoghna Das, Surajit Sengupta, Subhasis Sinha
We study structural transitions in a system of interacting particles arranged as a crystalline bilayer, as a function of the density and the distance between the layers. As…
