Correlation between kinetic fragility and Poisson's ratio from analysis of data for soft colloids
Arijit Mondal, Leishangthem Premkumar, Shankar P. Das
We consider the link between fragility and elasticity that follows from analysis of the data for a set of soft-colloid materials consisting of deformable spheres reported by Mattss…
Fragility index of a simple liquid from structural inputs
Leishangthem Premkumar, Shankar P. Das
We make a first principle calculation of the fragility index of a simple liquid using the structure of the supercooled liquid as an input. Using the density functional theory (…
Linking density functional and mode coupling models for supercooled liquids
Leishangthem Premkumar, Neeta Bidhoodi, Shankar P. Das
We compare predictions from two familiar models of the metastable supercooled liquid respectively constructed with thermodynamic and dynamic approach. In the so called density func…
Localization, disorder and boson peak in an amorphous solid
Leishangthem Premkumar, Shankar P. Das
We demonstrate using the classical density functional theory (DFT) model that an intermediate degree of mass localization in the amorphous state is essential for producing the boso…
