We present a model in which the immediate environment of a bistable system is a molecular chain which in turn is connected to a thermal environment of the Langevin form. The molecular chain consists of masses connected by harmonic or by anharmonic springs. The distribution, intensity, and...

A siteâ€“site representation of the Smoluchowskiâ€“Vlasov equation is proposed based on the generalized Langevin equation, and on the siteâ€“site Ornsteinâ€“Zernike equation for the molecular liquid. The method is applied for calculating the spaceâ€“time pair correlation...

A second-quantized, coupled oscillator model is presented which explicitly displays the structure of a second-quantized MTGLE theory. The Adelman ansatz [J. Chem Phys. 75, 5837 (1981)] for a quantum MTGLE response function is shown to generate the correct response function for the model. This...

In this paper we show the possibility of using very mild stochastic damping to stabilize long time step integrators for Newtonian molecular dynamics. More specifically, stable and accurate integrations are obtained for damping coefficients that are only a few percent of the natural decay rate of...

Shear dilatancy, a significant nonlinear behavior of nonequilibrium thermodynamics states, has been observed in nonequilibrium molecular dynamics (NEMD) simulations for liquid n-hexadecane fluid under extreme shear conditions. The existence of shear dilatancy is relevant to the relationship...
