The log of this quantity appears in the pseudo-Boltzmann factor for the Gibbs ensemble.
Monte Carlo simulations using the log of this quantity as a trial step give an N+1 term in the acceptance rule. The log of this quantity appears in the pseudo-Boltzmann factor for the Gibbs ensemble. For large N, the pair distribution function equals the probability density times this quantity squared. The grand canonical partition function equals the exponential of dimensionless fugacity times this dimensional quantity over a quantum version of it. The ideal gas entropy depends on the log of this quantity to the first power and the log of internal energy to the three-halves. It is the only (*) variable held fixed in the microcanonical, canonical, and grand canonical ensembles. This extensive quantity is the numerator of the translational partition function. This quantity, a natural variable for internal energy and Helmholtz free energy, is the one that gets exponentiated by the polytropic index. For 10 points, name this conjugate of pressure and inverse of density.
