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…

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…
