Nonextensive scalar field theories and dark energy models | | Christian Beck
; | | Date: |
17 Dec 2003 | | Journal: | Physica A340 (2004) 459-466 | | Subject: | cond-mat astro-ph | | Abstract: | Current astronomical measurements indicate that approximately 73% of the universe is made up of dark energy. Stochastically quantized self-interacting scalar fields can serve as suitable models to generate dark energy. We study a particular model where the scalar field theory underlying dark energy exhibits strongest possible chaotic behaviour. It is shown that the fluctuating chaotic field momenta obey a generalized (nonextensive) statistical mechanics, with an entropic index q given by q=3, respectively q=-1 if the escort formalism is used. | | Source: | arXiv, cond-mat/0312433 | | Services: | Forum | Review | PDF | Favorites | |
