The Boltzmann distribution is a foundational axiom of statistical mechanics and forms the mathematical basis for canonical sampling in molecular dynamics simulations; as a definitional and observational given of classical statistical physics, no citation is required.
The claim states that the Boltzmann distribution describes state populations in molecular dynamics simulations. This is a foundational principle of statistical mechanics and the theoretical basis of constant-temperature molecular dynamics (such as the canonical ensemble). Because it is a core foundational premise of statistical physics rather than a contested empirical finding, it is classified as common knowledge under Step 0, requiring no citations.
