Glassy dynamics, crossover temperature and density scaling in fragile glass-formers
Ankit Singh, Vinay Vaibhav, Swarn Lata Singh +1
We investigate the slowing down of dynamics in a glass-forming mixture interacting via an inverse-power-law (IPL) potential using a combination of theory and large-scale molecular…
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…
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…
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…
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…
Timescale bridging in atomistic simulations of epoxy polymer mechanics using non-affine deformation theory
Vinay Vaibhav, Timothy W. Sirk, Alessio Zaccone
Developing a deep understanding of macroscopic mechanical properties of amorphous systems which lack structural periodicity, has posed a key challenge, not only at the level of the…
Random close packing of binary hard spheres favors the stability of neutron-rich atomic nuclei
Carmine Anzivino, Vinay Vaibhav, Alessio Zaccone
In spite of the success of the Bethe-Weizsäcker mass formula in its modern numerical and predictive implementations, the common-knowledge principle that it is electrostatics which,…
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…
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…
Rheological response of a glass-forming liquid having large bidispersity
Vinay Vaibhav, Jürgen Horbach, Pinaki Chaudhuri
Using extensive numerical simulations, we investigate the flow behaviour of a model glass-forming binary mixture whose constituent particles have a large size ratio. The rheologica…
Finite-size effects in the diffusion dynamics of a glass-forming binary mixture with large size ratio
Vinay Vaibhav, Jürgen Horbach, Pinaki Chaudhuri
Extensive molecular dynamics (MD) computer simulations of an equimolar glass-forming AB mixture with large size ratio are presented. While the large A particles show a glass transi…
Equilibrium properties of blackbody radiation with an ultraviolet energy cut-off
Dheeraj Kumar Mishra, Nitin Chandra, Vinay Vaibhav
We study various equilibrium thermodynamic properties of blackbody radiation (i.e. a photon gas) with an ultraviolet energy cut-off. We find that the energy density, specific heat…
