Maximum entropy thermodynamicsIn physics, maximum entropy thermodynamics (colloquially, MaxEnt thermodynamics) views equilibrium thermodynamics and statistical mechanics as inference processes. More specifically, MaxEnt applies inference techniques rooted in Shannon information theory, Bayesian probability, and the principle of maximum entropy. These techniques are relevant to any situation requiring prediction from incomplete or insufficient data (e.g., , signal processing, spectral analysis, and inverse problems).
Quantum statistical mechanicsQuantum statistical mechanics is statistical mechanics applied to quantum mechanical systems. In quantum mechanics a statistical ensemble (probability distribution over possible quantum states) is described by a density operator S, which is a non-negative, self-adjoint, trace-class operator of trace 1 on the Hilbert space H describing the quantum system. This can be shown under various mathematical formalisms for quantum mechanics. One such formalism is provided by quantum logic.
Loi de distribution des vitesses de MaxwellEn théorie cinétique des gaz, la loi de distribution de vitesses de Maxwell quantifie la répartition statistique des vitesses des particules dans un gaz homogène à l'équilibre thermodynamique. Les vecteurs vitesse des particules suivent une loi normale. Cette loi a été établie par James Clerk Maxwell en 1860 et confirmée ultérieurement par Ludwig Boltzmann à partir de bases physiques qui fondent la physique statistique en 1872 et 1877.
