Matching the Vilkovisky-DeWitt Effective Action of Quantum Gravity to String Theory
Xavier Calmet, Elias Kiritsis, Folkert Kuipers +1
In this work, we discuss the matching of the Vilkovisky-DeWitt effective action of quantum gravity to an example of an ultra-violet complete theory of quantum gravity. We show how…
Quantum Hair During Gravitational Collapse
Xavier Calmet, Roberto Casadio, Stephen D. H. Hsu +1
We consider quantum gravitational corrections to the Oppenheimer-Snyder metric describing time-dependent dust ball collapse. The interior metric also describes Friedmann-Lemaitre-R…
Black Holes in Quantum Gravity
Xavier Calmet, Folkert Kuipers
We review some recent results obtained for black holes using effective field theory methods applied to quantum gravity, in particular the unique effective action. Black holes are c…
Quantum Hair from Gravity
Xavier Calmet, Roberto Casadio, Stephen D. H. Hsu +1
We explore the relationship between the quantum state of a compact matter source and of its asymptotic graviton field. For a matter source in an energy eigenstate, the graviton sta…
Quantum Gravitational Corrections to the Entropy of a Schwarzschild Black Hole
Xavier Calmet, Folkert Kuipers
We calculate quantum gravitational corrections to the entropy of black holes using the Wald entropy formula within an effective field theory approach to quantum gravity. The correc…
Stochastic Quantization on Lorentzian Manifolds
Folkert Kuipers
We embed Nelson's stochastic quantization in the Schwartz-Meyer second order geometry framework. The result is a non-perturbative theory of quantum mechanics on (pseudo)-Riemannian…
Quantum corrected equations of motion in the interior and exterior Schwarzschild spacetime
Xavier Calmet, Roberto Casadio, Folkert Kuipers
In this paper we derive the leading quantum gravitational corrections to the geodesics and the equations of motion for a scalar field in the spacetime containing a constant density…
Singularities in Quantum Corrected Space-times
Xavier Calmet, Roberto Casadio, Folkert Kuipers
In this paper we consider a static and regular fluid generating a locally spherically symmetric and time-independent space-time and calculate the leading quantum corrections to the…
Quantum Gravitational Corrections to a Star Metric and the Black Hole Limit
Xavier Calmet, Roberto Casadio, Folkert Kuipers
In this paper we consider the full set of quantum gravitational corrections to a star metric to second order in curvature. As we use an effective field theoretical approach, these…
Bifurcations in the RG-flow of QCD
Folkert Kuipers, Umut Gursoy, Yuri Kuznetsov
Bifurcation analysis is used to study an effective model of QCD with four-fermi interactions. Our analysis supports the scenario of a fixed point merger at the lower edge of th…
