Title: | Ensemble equivalence for non-Boltzmaniann distributions |
Authors: | Toral, Raúl CSIC ORCID | Keywords: | Jaynes principle Long-range interactions |
Issue Date: | 3-Feb-2006 | Publisher: | Elsevier | Citation: | Physica A 365, 85-90 (2006) | Abstract: | We discuss the possibility of using generalized canonical distributions, i.e., using other factors than exp(-βE), in order to compute the equilibrium properties of physical systems. It will be shown that some other choices can, in certain cases, lead to a simpler calculation of those properties. The corresponding equivalence between the canonical and the generalized canonical distributions is derived using well-known principles of statistical mechanics and we exemplify the method by deriving in a simple way the equilibrium properties of the long-range Ising model. | Description: | 6 pages.-- Final full-text version of the paper available at: http://dx.doi.org/10.1016/j.physa.2006.01.040. | URI: | http://hdl.handle.net/10261/6128 | DOI: | 10.1016/j.physa.2006.01.040 | ISSN: | 0378-4371 |
