Report

Functional renormalization group approach and gauge dependence in gravity theories

Autor: Barra, Vítor F., Lavrov, Peter M., Reis, Eduardo Antonio dos, Netto, Tibério de Paula, Shapiro, Ilya L.

Publikováno v: Phys. Rev. D 101, 065001 (2020)

We investigate the gauge symmetry and gauge fixing dependence properties of the effective average action for quantum gravity models of general form. Using the background field formalism and the standard BRST-based arguments, one can establish the spe

Quantum aspects of Yukawa model with scalar and axial scalar fields in curved spacetime

Autor: Buchbinder, Iosif L., Rodrigues, Andreza Rairis, Reis, Eduardo Antonio dos, Shapiro, Ilya L.

We study the Yukawa model with one scalar and one axial scalar fields, coupled to $N$ copies of Dirac fermions, in curved spacetime background. The theory possesses a reach set of coupling constants, including the scalar terms with odd powers of scal

Report

Gauge invariance of the background average effective action

Autor: Lavrov, Peter M., Reis, Eduardo Antonio dos, Netto, Tibério de Paula, Shapiro, Ilya L.

Using the background field method for the functional renormalization group approach in the case of a generic gauge theory, we study the background field symmetry and gauge dependence of the background average effective action, when the regulator acti

Stochastic quantization of a self-interacting nonminimal scalar field in semiclassical gravity

Autor: Reis, Eduardo Antonio dos, Krein, Gastão, Netto, Tibério de Paula, Shapiro, Ilya L.

We employ stochastic quantization for a self-interacting nonminimal massive scalar field in curved spacetime. The covariant background field method and local momentum space representation are used to obtain the Euclidean correlation function and eval
