Nesting of thermodynamic, structural, and dynamic anomalies in liquid silicon

Vasisht, Vishwas V.; Mathew, John; Sengupta, Shiladitya; Sastry, Srikanth (American Institute of Physics, 2014)

Anomalous behaviour in density, diffusivity, and structural order is investigated for silicon modeled by the Stillinger-Weber potential by performing molecular dynamics simulations. As previously reported in the case of ...
Role of Structure and Entropy in Determining Differences in Dynamics for Glass Formers with Different Interaction Potentials

Banerjee, Atreyee; Sengupta, Shiladitya; Sastry, Srikanth; Bhattacharyya, Sarika Maitra (American Physical Society, 2014)

We present a study of two model liquids with different interaction potentials, exhibiting similar structure but significantly different dynamics at low temperatures. By evaluating the configurational entropy, we show that ...
Unraveling the success and failure of mode coupling theory from consideration of entropy

Nandi, Manoj Kumar; Banerjee, Atreyee; Sengupta, Shiladitya; Sastry, Srikanth; Bhattacharyya, Sarika Maitra (American Institute of Physics, 2015)

We analyze the dynamics of model supercooled liquids in a temperature regime where predictions of mode coupling theory (MCT) are known to be valid qualitatively. In this regime, the Adam-Gibbs (AG) relation, based on an ...
