Higher-order regularity in local and nonlocal quantum gravity
Nicolò Burzillà, Breno L. Giacchini, Tibério de Paula Netto +1
In the present work we investigate the Newtonian limit of higher-derivative gravity theories with more than four derivatives in the action, including the non-analytic logarithmic t…
Newtonian potential in higher-derivative quantum gravity
Nicolò Burzillà, Breno L. Giacchini, Tibério de Paula Netto +1
We hereby derive the Newtonian metric potentials for the fourth-derivative gravity including the one-loop logarithm quantum corrections. It is explicitly shown that the behavior of…
On the Vilkovisky-DeWitt approach and renormalization group in effective quantum gravity
Breno L. Giacchini, Tibério de Paula Netto, Ilya L. Shapiro
The effective action in quantum general relativity is strongly dependent on the gauge-fixing and parametrization of the quantum metric. As a consequence, in the effective approach…
Light bending by a slowly rotating source in quadratic theories of gravity
Luca Buoninfante, Breno L. Giacchini
In this paper we study the light bending caused by a slowly rotating source in the context of quadratic theories of gravity, in which the Einstein--Hilbert action is extended by ad…
Vilkovisky unique effective action in quantum gravity
Breno L. Giacchini, Tibério de Paula Netto, Ilya L. Shapiro
The divergent part of the one-loop Vilkovisky unique effective action for quantum Einstein gravity is evaluated in the general parametrization of the quantum field, including the s…
