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…
Saturation of number variance in embedded random matrix ensembles
Ravi Prakash, Akhilesh Pandey
We study fluctuation properties of embedded random matrix ensembles of non-interacting particles. For ensemble of two non-interacting particle systems, we find that unlike the spec…
Insulating phase in SrIrO: An investigation using critical analysis and magnetocaloric effect
Imtiaz Noor Bhatti, A. K. Pramanik
The nature of insulating phase in 5 based SrIrO is quite debated as the theoretical as well as experimental investigations have put forward evidences in favor of both ma…
Nonequilibrium low temperature phase in pyrochlore iridate YIrO: Possibility of glass-like dynamics
Harish Kumar, A. K. Pramanik
Geometrical frustration and spin-orbit coupling effect together play vital role to influence properties in pyrochlore based iridium oxides. Here we have investigated detailed struc…
Ergodicity and slow diffusion in a supercooled liquid
Neeta Bidhoodi, Shankar P. Das
A model for the slow dynamics of the supercooled liquid is formulated in terms of the standard equations of fluctuating nonlinear hydrodynamics (FNH) with the inclusion of an extra…
