Transport coefficients in AdS/CFT and quantum gravity corrections due to a functional measure
Iberê Kuntz, Roldao da Rocha
The presence of a functional measure is scrutinized on both sides of the dual gauge/gravity correspondence. Corrections to the transport coefficients in relativistic hydrodynamics…
Minimum length (scale) in Quantum Field Theory, Generalized Uncertainty Principle and the non-renormalisability of gravity
Roberto Casadio, Wenbin Feng, Ibere Kuntz +1
The notions of minimum geometrical length and minimum length scale are discussed with reference to correlation functions obtained from in-in and in-out amplitudes in quantum field…
Background independence and field redefinitions in quantum gravity
Roberto Casadio, Alexander Kamenshchik, Iberê Kuntz
It is generally believed that a full-fledged theory of quantum gravity should exhibit background independence and diffeomorphism invariance. In its most general form, the latter co…
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…
Covariant singularities: a brief review
Roberto Casadio, Alexander Kamenshchik, Iberê Kuntz
The Hawking-Penrose theorem is not covariant under field redefinitions. Should the invariance under such transformations be a true principle in Nature, spacetime singularities beco…
