Is -generalized statistical field theory complete?
P. R. S. Carvalho
In this Letter we introduce some field-theoretic approach for computing the critical properties of -generalized systems undergoing continuous phase transitions, namely $γ_…
Squeezing as a probe of the universality hypothesis
P. A. L. Mourão, H. A. S. Costa, P. R. S. Carvalho
We compute analytically the radiative quantum corrections, up to next-to-leading loop order, to the universal critical exponents for both massless and massive O() scala…
Experimental validation of nonextensive statistical field theory: applications to manganites
P. R. S. Carvalho
In this Letter we validate experimentally the nonextensive statistical field theory, a new general field-theoretic approach introduced recently in the literature. With such an appr…
Nonextensive percolation and Lee-Yang edge singularity from nonextensive scalar field theory
P. R. S. Carvalho
We compute the critical exponents for nonextensive scalar field theory for all loop orders and . We apply the results for both nonextensive percolation and Le…
Nonextensive statistical field theory
P. R. S. Carvalho
We introduce a field-theoretic approach for describing the critical behavior of nonextensive systems, systems displaying global correlations among their degrees of freedom, encoded…
Diffeomorphism symmetry effect on the O(N ) universality class
H. A. S. Costa, P. R. S. Carvalho
We probe the effect of diffeomorphism symmetry on the critical exponents values for massive O() scalar field theories in curved spacetime. We apply field-theoretic reno…
