Negative heat capacity and non-extensive kinetic theory | R. Silva

31 May 2003 | Journal: | Phys.Lett. A313 (2003) 393-396 | Subject: | Astrophysics; Statistical Mechanics | astro-ph cond-mat.stat-mech | Affiliation: | UERN) and J. S. Alcaniz (UFRN | Abstract: | The negative nature of the heat capacity $C_V$ of thermodynamically isolated self-gravitating systems is rediscussed in the framework of a non-extensive kinetic theory. It is found that the dependence of $C_V$ on the non-extensive parameter $q$ gives rise to a negative branch with the critical value corresponding to $q = 5/3$ ($C_V o - infty$). | Source: | arXiv, astro-ph/0306009 | Other source: | [GID 1011535] astro-ph/0306009 | Services: | Forum | Review | PDF | Favorites |
