Transport coefficients at Metastable Densities from models of Generalized Hydrodynamics
Sudha Srivastava, Shankar P. Das
In the present work we compute the enhancement in the long time transport coefficients due to correlated motion of fluid particles at high density. The fully wave vecor dependent e…

Fragility and Boson Peak formation in a Supercooled Liquid
Sudha Srivastava, Shankar P. Das
We analyze results for the Boson Peak from the neutron time of flight spectroscopy data on Ge-As-Se, and Raman spectra data on m-TCP and OTP, using a recent mode coupling model tha…

Temperature dependence of the Power law exponent of relaxation in a supercooled Liquid
Sudha Srivastava, Shankar P. Das
The dynamics of Lennard-Jones fluid is studied through extended mode coupling theory (MCT) with the inclusion of the slow mode of defect density. Inclusion of defect density facili…
