Nonextensive Entropy, Prior PDFs and Spontaneous Symmetry Breaking
Published 2008-10-06, updated 2008-10-26Version 2
We show that using nonextensive entropy can lead to spontaneous symmetry breaking when a parameter changes its value from that applicable for a symmetric domain, as in field theory. We give the physical reasons and also show that even for symmetric Dirichlet priors, such a defnition of the entropy and the parameter value can lead to asymmetry when entropy is maximized.
