Towards Perturbative Unimodular Poincaré Gauge Theories with Propagating Torsion
Arthur F. Vieira, Antonio D. Pereira, Reinhard Alkofer
We study the one-loop relation between an effective-field-theory extension of Poincaré gauge theories of gravity with propagating torsion and its unimodular counterpart. In the Ein…
Fate of chiral symmetry in Riemann-Cartan geometry
Gustavo P. de Brito, Antonio D. Pereira, Arthur F. Vieira
We study the mechanism of chiral symmetry breaking for fermionic systems in a gravitational background with curvature and torsion. The analysis is based on a scale-dependent effect…
Frontiers of Quantum Gravity: shared challenges, converging directions
Jan de Boer, Bianca Dittrich, Astrid Eichhorn +10
Understanding the quantum nature of spacetime and gravity remains one of the most ambitious goals of theoretical physics. It promises to provide key new insights into fundamental p…
Evidence for a novel shift-symmetric universality class from the functional renormalization group
Cristobal Laporte, Nora Locht, Antonio D. Pereira +1
Wetterich's equation provides a powerful tool for investigating the existence and universal properties of renormalization group fixed points exhibiting quantum scale invariance. Mo…
Towards background field independence within the Gribov horizon
Igor F. Justo, Antonio D. Pereira, Rodrigo F. Sobreiro
We introduce a background gauge akin to the Landau-DeWitt gauge but deformed by the presence of a gauge parameter for the quantization of Euclidean Yang-Mills theories. In the limi…
Scalar-Tensor theories within Asymptotic Safety
Cristobal Laporte, Antonio D. Pereira, Frank Saueressig +1
Asymptotic Safety provides an elegant mechanism for obtaining a consistent high-energy completion of gravity and gravity-matter systems. Following the initial idea by Steven Weinbe…
