Stiffness induced structures and morphological transitions in semiflexible polymers
Biman Bagchi
Semiflexible polymers in poor solvents exhibit a rich variety of collapsed morphologies, including globules, toroids, and rodlike bundles, arising from the competition between attr…
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…
Dynamics of Nonequilibrium Dimerization of Model Polymer Chains
Sangita Mondal, Ved Mahajan, Biman Bagchi
Dimerization and subsequent aggregation of polymers and biopolymers often occur under nonequilibrium conditions. When the initial state of the polymer is not collapsed or the final…
