Nonlinear generalized Langevin equations

- R. Zwanzig
- Physics
- 1 November 1973

Exact generalized Langevin equations are derived for arbitrarily nonlinear systems interacting with specially chosen heat baths. An example is displayed in which the Langevin equation is nonlinear… Expand

High‐Temperature Equation of State by a Perturbation Method. I. Nonpolar Gases

- R. Zwanzig
- Chemistry
- 1 August 1954

The perturbation theory described in a previous article is applied to the calculation of the equation of state at high temperature of a polar gas. The electrostatic dipolar potential is considered to… Expand

Ensemble Method in the Theory of Irreversibility

- R. Zwanzig
- Chemistry
- 1 November 1960

We describe a new formulation of methods introduced in the theory of irreversibility by Van Hove and Prigogine, with the purpose of making their ideas easier to understand and to apply. The main tool… Expand

Memory Effects in Irreversible Thermodynamics

- R. Zwanzig
- Physics
- 15 November 1961

A new generalization of Onsager's theory of irreversible processes is presented. The main purpose is to allow for memory effects or causal time behavior, so that the response to a thermodynamic force… Expand

Diffusion past an entropy barrier

- R. Zwanzig
- Chemistry
- 1 May 1992

Diffusion in a tube or channel of varying cross section has been treated, by Fick and Jacobs, as one-dimensional diffusion past an entropy barrier determined by the tube cross-sectional area or… Expand

Hydrodynamic Theory of the Velocity Correlation Function

- R. Zwanzig, M. Bixon
- Physics
- 1 November 1970

The velocity correlation function of an atom in a simple liquid is calculated using a frequency-dependent version of the Stokes-Einstein formula. Stokes's law for the frictional force on a moving… Expand

High‐Frequency Elastic Moduli of Simple Fluids

- R. Zwanzig, R. Mountain
- Chemistry
- 15 December 1965

This article presents a calculation of the infinite‐frequency elastic moduli of monatomic fluids. When the intermolecular potential has the standard Lennard‐Jones form, the elastic moduli are shown… Expand
