Diffusion in Rugged Energy Landscapes in the Presence of Spatial Correlations : A Surprising Route to Zwanzig's Mean-Field Prediction
Biman Bagchi
Diffusion in rugged free-energy landscapes is central to diverse problems in chemical physics, biomolecular dynamics, polymer transport and numerous disordered systems. Zwanzig's w…

From Frequency Dependent Specific Heat to Fictive Temperature of a Glassy Liquid
Biman Bagchi
Upon rapid quenching of temperature of a glass forming liquid, the system falls out of equilibrium due its finite relaxation time. Additionally, the relaxation becomes progressivel…

Diffusion-entropy scaling across dimensions
Nayana Venkatareddy, Mohd Moid, Prabal K. Maiti +1
A quantitative relationship between the diffusion coefficient of a tagged particle in a liquid and the entropy of that liquid has long been sought, as it would allow entrop…
