On the Relation Between the Second Law of Thermodynamics and Classical and Quantum Mechanics

摘要: This article is devoted to the relation between second law of thermodynamics, which applies closed macroscopic systems consisting an extremely large number particles, such as liquids or gases, and classical quantum mechanics, are theories that describe interacting particles on a microscopic level.In textbooks statistical finds often arguments based phase space ergodicity in order justify thermodynamics. However, basic equations motion mechanics deterministic reversible, while thermodynamics irreversible not deterministic, because it states system forgets its past when approaching equilibrium. I will argue all "derivations” from include additional assumptions part mechanics. The same holds for Boltzmann's H-theorem. Furthermore, coarse-graining phase-space used deriving cannot be viewed expression our ignorance details state system, but reflects fact fully specified by using only finite bits, implied concept entropy, related different microstates can have. While described Schroedinger equation, puts this latter statement firm ground, explain irreversibility stochasticity inherent law.
