Relation between Entropy, Diffusion and Relaxation Kinetics
Subhajit Acharya, Biman Bagchi
Intermolecular correlations lower values of both diffusion and entropy. We present an analysis of the existing relations between long-time diffusion (D) and entropy. S. A recently…
Stokes Law at Molecular Length Scales: Effects of Intermolecular Interactions and Linear Response Theory
Subhajit Acharya, Biman Bagchi
The celebrated Stokes Law (SL) of hydrodynamics predicts that the velocity of a particle pulled through a liquid by an external force, Fex, is directly proportional to the force an…
Friction and Memory Effects in Homogeneous Gas-Liquid Nucleation: Quest for Quantitative Rate Calculation
Subhajit Acharya, Biman Bagchi
The task of a first principles theoretical calculation of the rate of gas to liquid nucleation has remained largely incomplete despite the existence of reliable results from unbias…
Examination of Boltzmann's H-Function: Dimensionality and Interaction Sensitivity Dependence, and a comment on his H-Theorem
Shubham Kumar, Subhajit Acharya, Biman Bagchi
Boltzmann's H-Theorem, formulated 150 years ago in terms of H-function that also bears his name, is one of the most celebrated theorems of science and paved the way for the develop…
Diffusion in the Presence of Correlated Returns in a Two-dimensional Energy Landscape and non-Monotonic Friction Dependence: Examination of Simulation Results by a Random Walk Model
Subhajit Acharya, Biman Bagchi
Diffusion in a multidimensional energy surface with minima and barriers is a problem of importance in statistical mechanics and also has wide applications, such as protein folding.…
Study of Entropy-Diffusion Relation in a Deterministic Hamiltonian System through Microscopic Analysis
Subhajit Acharya, Biman Bagchi
Although an intimate relation between entropy and diffusion has been advocated for many years and even seems to have been verified in theory and experiments, a quantitatively relia…
Altered Dielectric Behaviour, Structure and Dynamics of Nanoconfined Dipolar Liquids: Signatures of Enhanced Cooperativity
Sayantan Mondal, Subhajit Acharya, Biman Bagchi
Spherical confinement can alter the properties of a dipolar fluid in several different ways. In an atomistic molecular dynamics simulation study of two different dipolar liquids (S…
In search of the origin of long-time power-law decay in DNA solvation dynamics
Saumyak Mukherjee, Sayantan Mondal, Subhajit Acharya +1
Experiments reveal that DNA solvation dynamics (SD) is characterized by multiple time scales ranging from a few ps to hundreds of ns and in some cases even up to microseconds. The…
