We show that Nosromane-bar mechanics provides a link between computer simulations of nonequilibrium processes and real-world experiments. Reversible Nose-bar equations of motion, when used to constrain non- equilibrium boundary regions, generate stable dissipative behavior within an adjoining bulk sample governed by Newton's equations of motion. Thus, irreversible behavior consistent with the second law of thermodynamics arises from completely reversible microscopic motion. Loschmidt's…

Nonequilibrium Time Reversibility with Maps and Walks

Time-reversible dynamical simulations of nonequilibrium systems exemplify both Loschmidt’s and Zermélo’s paradoxes. That is, computational time-reversible simulations invariably produce solutions

Time-reversible Molecular Motion and Macroscopic Irreversibility

The thermodynamic irreversibility of molecular processes involving heat transfer is established by incorporating time-reversible dynamical thermostats in the equations of motion. It is then possible

Microscopic Time-Reversibility and Macroscopic Irreversibility — Still a Paradox?

Microscopic time reversibility and macroscopic irreversibility are a paradoxical combination. This was first observed by J. Loschmidt in 1876 and was explained, for conservative systems, by L.

Ludwig Boltzmann, Transport Equation and the Second law

Ludwig Boltzmann had a hunch that irreversibility exhibited by a macroscopic system arises from the reversible dynamics of its microscopic constituents. He derived a nonlinear integro-differential

Coexistence of Conservative and Dissipative Behavior in Reversible Dynamical Systems: Time-Reversible Thermostated Nos\'e-Hoover Oscillators

We use nonequilibrium molecular dynamics to analyze and illustrate the qualitative differences between the one-thermostat and two-thermostat versions of equilibrium and nonequilibrium

Origin of the thermodynamic time arrow demonstrated in a realistic statistical system

This article derives and explains the emergence of one-time-direction macroscopic evolution of a classical system of two mixed gases having different temperatures. The analysis performed at the

Irreversible Processes from Reversible Mechanics

We describe and illustrate methods for treating many-body irreversible processes using time-reversible deterministic Nose-Hoover thermostats. In phase space, Lyapunov-unstable multifractal strange

Nosé–Hoover nonequilibrium dynamics and statistical mechanics

At equilibrium Nosé's 1984 revolutionary thermostat idea linked Newton's mechanics with Gibbs' statistical mechanics. His work expanded the scope of isothermal and isobaric simulations. Nosé–Hoover
