Statistical Weight

In statistical mechanics, the statistical weight is the relative probability (possibly unnormalized) of a particular feature of a state. If the energy associated with the feature is ΔE, the statistical weight is given by the Boltzmann factor e-ΔE/kT, where k is the Boltzmann constant and T is the temperature in kelvin.

The statistical weight is a convenient shorthand that is often used in transfer matrix solutions of problems in statistical mechanics.


Famous quotes containing the word weight:

    “A German immersed in any civilization different from his own loses a weight equivalent in volume to the amount of intelligence he displaces.”
    —José Bergamín (1895–1983)
