Theory of distribution skewness effect on polydisperse random close packing
Vinay Vaibhav, Carmine Anzivino, Alessio Zaccone
We investigate the random close packing density, , of polydisperse hard sphere systems using a theoretical framework based on the equilibrium model of crowding. We…
Atomistic Framework for Glassy Polymer Viscoelasticity Across Twenty Frequency Decades
Ankit Singh, Vinay Vaibhav, Caterina Czibula +6
Glassy polymers are central to engineering applications, yet their viscoelastic response over broad frequency and temperature ranges remains difficult to characterize. We extend no…
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…
Viscosity of polymer melts using non-affine theory based on vibrational modes
Ankit Singh, Vinay Vaibhav, Alessio Zaccone
Viscosity, a fundamental transport and rheological property of liquids, quantifies the resistance to relative motion between molecular layers and plays a critical role in understan…
Experimental identification of topological defects in 2D colloidal glass
Vinay Vaibhav, Arabinda Bera, Amelia C. Y. Liu +3
Topological defects are singularities within a field that cannot be removed by continuous transformations. The definition of these irregularities requires an ordered reference conf…
