Are You Living in a Simulation? Many works of science fiction as well as some forecasts by serious technologists and futurologists predict that enormous amounts of computing power will be available in the future. Let us suppose for a moment that these predictions are correct. One thing that later generations might do with their super-powerful computers is run detailed simulations of their forebears or of people like their forebears.

Advanced Search Boolean Search Within all of the search fields, the Boolean Operators AND (also + or &), OR, and NOT (also -) allow you to perform searches that specify logical relationships between terms. By default, an AND relationship between each of the terms you enter is established except for the Author field (see Author Searching below). New Journal of Physics Understanding nonequilibrium systems and the consequences of irreversibility for the system’s behavior as compared to the equilibrium case, is a fundamental question in statistical physics. Here, we investigate two types of nonequilibrium phase transitions, a second-order and an infinite-order phase transition, in a prototypical q-state vector Potts model which is driven out of equilibrium by coupling the spins to heat baths at two different temperatures. We discuss the behavior of the quantities that are typically considered in the vicinity of (equilibrium) phase transitions, like the specific heat, and moreover investigate the behavior of the entropy production (EP), which directly quantifies the irreversibility of the process.
