Bridging the Gap Between the Mode Coupling and the Random First Order Transition Theories of Structural Relaxation in Liquids
Sarika Maitra Bhattacharyya, Biman Bagchi, Peter G. Wolynes
A unified treatment of structural relaxation in a deeply supercooled glassy liquid is developed which extends the existing mode coupling theory (MCT) by incorporating the effects o…
Anisotropic Local Stress and Particle Hopping in a Deeply Supercooled Liquid
Sarika Bhattacharyya, Biman Bagchi
The origin of the microscopic motions that lead to stress relaxation in deeply supercooled liquid remains unclear. We show that in such a liquid the stress relaxation is locally an…
Relaxation in open one-dimensional systems
Prasanth P Jose, Biman Bagchi
A new master equation to mimic the dynamics of a collection of interacting random walkers in an open system is proposed and solved numerically.In this model, the random walkers int…
Anomalous Temperature Dependence of Heat Capacity During a Cooling-Heating Cycle in Glassy Systems
Dwaipayan Chakrabarti, Biman Bagchi
Anomalous temperature dependence of heat capacity of glassy systems during a cooling-heating cycle has remained an ill-understood problem for a long time. Most of the features obse…
Relationship between Entropic Bottleneck in Free Energy Landscape, Nonexponential Relaxation and Fragility of Glass-Forming Liquids
Dwaipayan Chakrabarti, Biman Bagchi
A mesoscopic model is proposed to explain the anomalous dynamics in a supercooled liquid as its glass transition temperature is approached from above. The model is based on the ass…
Evidence for Bound and Free Water Species in the Hydration Shell of an Aqueous Micelle
Sundaram Balasubramanian, Subrata Pal, Biman Bagchi
Our atomistic molecular dynamics simulations reveal the existence of bound and free water molecules in the hydration layer of an aqueous micelle. The bound water molecules can be e…
