Multiplicity (statistical mechanics)
Number of microstates for a given macrostate of a thermodynamic system / From Wikipedia, the free encyclopedia
In statistical mechanics, multiplicity (also called statistical weight) refers to the number of microstates corresponding to a particular macrostate of a thermodynamic system.[1] Commonly denoted , it is related to the configuration entropy of an isolated system [2] via Boltzmann's entropy formula
where is the entropy and is Boltzmann's constant.
