Shockwave Compression and Joule-Thomson Expansion
Wm. G. Hoover, Carol G. Hoover, Karl P. Travis
Structurally-stable atomistic one-dimensional shockwaves have long been simulated by injecting fresh cool particles and extracting old hot particles at opposite ends of a simulatio…
Why Instantaneous Values of the "Covariant" Lyapunov Exponents Depend upon the Chosen State-Space Scale
Wm. G. Hoover, Carol G. Hoover
We explore a simple example of a chaotic thermostated harmonic-oscillator system which exhibits qualitatively different local Lyapunov exponents for simple scale-model constant-vol…
Time-Reversible Random Number Generators : Solution of Our Challenge by Federico Ricci-Tersenghi
Wm. G. Hoover, Carol G. Hoover
Nearly all the evolution equations of physics are time-reversible, in the sense that a movie of the solution, played backwards, would obey exactly the same differential equations a…
Time-Symmetry Breaking in Hamiltonian Mechanics
Wm. G. Hoover, Carol G. Hoover
Hamiltonian trajectories are strictly time-reversible. Any time series of Hamiltonian coordinates {q} satisfying Hamilton's motion equations will likewise satisfy them when played…
Hamiltonian Thermostats Fail to Promote Heat Flow
Wm. G. Hoover, Carol G. Hoover
Hamiltonian mechanics can be used to constrain temperature simultaneously with energy. We illustrate the interesting situations that develop when two different temperatures are imp…
