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…

Parameter estimation in an anisotropic expanding spacetime
O. P. de Sá Neto, I. G. da Paz, P. R. S. Carvalho +1
In this work, we investigate how the anisotropy affects the cosmological parameters estimation. Here the anisotropy is incorporated as a small gravitational disturbance. We calcula…

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…
