21. The partition function is the volume of configurations, each configuration weighted by its Boltzmann weight. 22. It is derived in the same way as the partition function for the canonical ensemble. 23. In quantum mechanics, the partition function can be more formally written as a basis ): 24. Z _ t is the partition function , defined as: 25. For atoms the partition function values can be found in the NIST Atomic Spectra Database. 26. Thus they can be used as a kind of partition function for nonequilibrium steady states. 27. We want to know when the choice of sign of the partition function is ill-defined. 28. Applications on partition functions for strongly coupled correlated systems have shown promise of the method. 29. If hard-spheres are assumed, the partition function Q is 30. With the partition function obtained, a variety of physical quantities can be extracted as previously described.
