Inflation as a spontaneous symmetry breaking of Weyl symmetry
A. Barnaveli, S. Lucat, T. Prokopec
In this paper we study a novel realization of inflation, based on Weyl invariant gravity with torsion. We show that requiring the classical action for the scalar field to be Weyl i…
Discreteness of Black Hole Microstates
Gerard `t Hooft
It is explained that, for black holes much heavier than the Planck mass, black hole microstates can be well understood without string theory. It is essential to understand the anti…
Strong cosmic censorship in charged black-hole spacetimes: still subtle
Vitor Cardoso, Joao L. Costa, Kyriakos Destounis +2
It was recently shown that Strong Cosmic Censorship may be violated in highly charged black-hole spacetimes living in a universe with a positive cosmological constant. Several foll…
Failure of the stochastic approach to inflation beyond slow-roll
Diego Cruces, Cristiano Germani, Tomislav Prokopec
After giving a pedagogical review we clarify that the stochastic approach to inflation is generically reliable only at zeroth order in the (geometrical) slow-roll parameter i…
Kinetic theory and classical limit for real scalar quantum field in curved space-time
Pavel Friedrich, Tomislav Prokopec
Starting from a real scalar quantum field theory with quartic self-interactions and non-minimal coupling to classical gravity, we define four equal-time, spatially covariant phase-…
Inflation in an effective gravitational model & asymptotic safety
Lei-Hua Liu, Tomislav Prokopec, Alexei A. Starobinsky
We consider an inflationary model motivated by quantum effects of gravitational and matter fields near the Planck scale. Our Lagrangian is a re-summed version of the effective Lagr…
The Graviton Tail almost Completely Wags the Dog
S. P. Miao, T. Prokopec, R. P. Woodard
One graviton loop corrections to the vacuum polarization on de Sitter show two interesting infrared effects: a secular enhancement of the photon electric field strength and a long…
Conformal symmetry and the cosmological constant problem
Stefano Lucat, Tomislav Prokopec, Bogumila Swiezewska
We argue that, when a theory of gravity and matter is endowed with (classical) conformal symmetry, the fine tuning required to obtain the cosmological constant at its observed valu…
