Blackbody radiation in nonextensive Tsallis statistics: Exact solution

An exact analysis of n-dimensional blackbody radiation in the recently proposed nonextensive Tsallis statistics is given here. Thus, the main relationships of blackbody radiation are generalized in the Tsallis context. In particular, it is verified that the relation between pressure, volume, and internal energy is form invariant with respect to the nonextensive entropic index, q. The results and procedure presented here are expected to be useful in the discussion of nonextensive systems possessing large or infinite numbers of degrees of freedom. (C) 1998 Elsevier Science B.V.
