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…
Microscopic constitutive theory of stress overshoot, yielding, and strain hardening in amorphous materials
Ankit Singh, Valeriy V. Ginzburg, Alessio Zaccone
We develop a microscopic constitutive theory for the nonlinear deformation of metallic and polymer glasses based on nonaffine elasticity coupled to irreversible many-body relaxatio…
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…
How attractive and repulsive interactions affect structure ordering and dynamics of glass-forming liquids?
Ankit Singh, Yashwant Singh
The theory developed in our previous papers is applied in this paper to investigate the dependence of slowing down of dynamics of glass-forming liquids on the attractive and repuls…
Emergence of cooperatively reorganizing cluster and super-Arrhenius dynamics of fragile supercooled liquids
Ankit Singh, Sarika Maitra Bhattacharyya, Yashwant Singh
In this paper we develop a theory to calculate the structural relaxation time τ α of fragile su percooled liquids. Using the information of the configurational entropy and structur…
Super-Arrhenius behaviour of molecular glass formers
Ankit Singh, Yashwant Singh
A theory is developed to calculate values of the potential energy barriers to structural relaxation in molecular glass formers from the data of static pair correlation function. Th…
