Euclidean actions and static black hole entropy in teleparallel theories
Iberê Kuntz, Gregorio Paci, Omar Zanusso
It is well-known that the results by Bekenstein, Gibbons and Hawking on the thermodynamics of black holes can be reproduced quite simply in the Euclidean path integral approach to…
When gravitational decoupling and quantum gravity (re)unite
R. Casadio, I. Kuntz, R. da Rocha
The effective action for quantum gravity coupled to matter contains corrections arising from the functional measure. We analyse the effect of such corrections for anisotropic self-…
Binary mergers in bootstrapped Newtonian gravity: mass gap and black hole area law
Roberto Casadio, Iberê Kuntz, Octavian Micu
We study binary mergers in bootstrapped Newtonian gravity, where higher-order couplings are added to the non-relativistic Lagrangian for the Newtonian potential. In this theory, th…
Approximating compact objects in bootstrapped Newtonian gravity: use of the canonical potential
Roberto Casadio, Iberê Kuntz, Octavian Micu
We consider compact objects in a classical and non-relativistic generalisation of Newtonian gravity, dubbed bootstrapped Newtonian theory, which includes higher-order derivative in…
Effective metric outside bootstrapped Newtonian sources
Roberto Casadio, Andrea Giusti, Iberê Kuntz +1
We determine the complete space-time metric from the bootstrapped Newtonian potential generated by a static spherically symmetric source in the surrounding vacuum. This metric cont…
Absence of covariant singularities in pure gravity
Roberto Casadio, Alexander Kamenshchik, Iberê Kuntz
The assumptions of the Hawking-Penrose singularity theorem are not covariant under field redefinitions. Thus we propose to study singularities in field space, where the spacetime m…
Bootstrapped Newtonian quantum gravity
Roberto Casadio, Iberê Kuntz
We compute quantum corrections for the gravitational potential obtained by including a derivative self-coupling in its classical dynamics as a toy model for analysing quantum gravi…
Non-smooth gravity and parity violation
Iberê Kuntz
A conservative extension of general relativity is proposed by alleviating the differentiability of the metric and allowing for non-smooth solutions. We show that these metrics brea…
Quantum Corrections to the Gravitational Backreaction
Iberê Kuntz
Effective Field Theory techniques are used to study the leading order quantum corrections to the gravitational wave backreaction. The effective stress-energy tensor is calculated a…
What is modified gravity and how to differentiate it from particle dark matter?
Xavier Calmet, Iberê Kuntz
An obvious criterion to classify theories of modified gravity is to identify their gravitational degrees of freedom and their coupling to the metric and the matter sector. Using th…
