Two-temperature pedagogical cell models, extensions of the equilibrium Einstein model of solid state physics, can allow nonequilibrium hot-to-cold heat transfer. These heat-flow models can be driven by thermostatted temperature differences, for instance between horizontal and vertical degrees of ...
In response to the 2024 Snook Prize Problem, this paper compares the mixing rates of six simple numerical algorithms that produce an ergodic Gaussian distribution of position and momentum for a one-dimensional harmonic oscillator. A hundred thousand initial conditions spread uniformly over the co ...
The $1000 Ian Snook Prize for 2020 will be awarded to the author(s) of the most interesting paper exploring pairs of relatively simple, but fractal, models of nonequilibrium systems, dissipative time-reversible Baker Maps and their equivalent stochastic random walks. Two-dimensional deterministic ...
