Two-Form Asymptotic Symmetries and Scalar Soft Theorems
Dario Francia, Carlo Heissenberg
We investigate the large gauge transformations of a two-form gauge field in four-dimensional Minkowski space. Our goal is to establish a connection between these asymptotic symmetr…
Stable wormholes in scalar-tensor theories
Gabriele Franciolini, Lam Hui, Riccardo Penco +2
We reconsider the issue of whether scalar-tensor theories can admit stable wormhole configurations supported by a non-trivial radial profile for the scalar field. Using a recently…
Effective Field Theory of Black Hole Quasinormal Modes in Scalar-Tensor Theories
Gabriele Franciolini, Lam Hui, Riccardo Penco +2
The final ringdown phase in a coalescence process is a valuable laboratory to test General Relativity and potentially constrain additional degrees of freedom in the gravitational s…
AdS Asymptotic Symmetries from CFT Mirrors
Rashmish K. Mishra, Arif Mohd, Raman Sundrum
We study Kac-Moody asymptotic symmetries and memory effects in gauge theory and (when accompanied by 4D gravity) in its holographic CFT dual. W…
Fakeons, Microcausality And The Classical Limit Of Quantum Gravity
Damiano Anselmi
We elaborate on the idea of fake particle and study its physical consequences. When a theory contains fakeons, the true classical limit is determined by the quantization and a subs…
New infra-red enhancements in 4-derivative gravity
Alberto Salvio, Alessandro Strumia, Hardi Veermae
4-derivative gravity provides a renormalizable theory of quantum gravity at the price of introducing a physical ghost, which could admit a sensible positive-energy quantization. To…
Back-Reaction of Super-Hubble Cosmological Perturbations Beyond Perturbation Theory
Robert Brandenberger, Leila L. Graef, Giovanni Marozzi +1
We discuss the effect of super-Hubble cosmological fluctuations on the locally measured Hubble expansion rate. We consider a large bare cosmological constant in the early universe…
Long distance behavior of -model correlators in de Sitter space and the resummation of secular terms
Diana López Nacir, Francisco D. Mazzitelli, Leonardo G. Trombetta
We analyze the long distance behavior of the two-point functions for an interacting scalar model in de Sitter spacetime. Following our previous work, this behavior is analyz…
Behind Horndeski: Structurally Robust Higher Derivative EFTs
Luca Santoni, Enrico Trincherini, Leonardo G. Trombetta
Higher derivative scalar interactions can give rise to interesting cosmological scenarios. We present a complete classification of such operators that can yield sizeable effects wi…
Quantum Gravity, Fakeons And Microcausality
Damiano Anselmi, Marco Piva
We investigate the properties of fakeons in quantum gravity at one loop. The theory is described by a graviton multiplet, which contains the fluctuation of the metric, a m…
Spectrum of the Laplace-Beltrami Operator and the Phase Structure of Causal Dynamical Triangulation
Giuseppe Clemente, Massimo D'Elia
We propose a new method to characterize the different phases observed in the non-perturbative numerical approach to quantum gravity known as Causal Dynamical Triangulation. The met…
The Ultraviolet Behavior Of Quantum Gravity
Damiano Anselmi, Marco Piva
A theory of quantum gravity has been recently proposed by means of a novel quantization prescription, which is able to turn the poles of the free propagators that are due to the hi…
Fakeons And Lee-Wick Models
Damiano Anselmi
The "fakeon" is a fake degree of freedom, i.e. a degree of freedom that does not belong to the physical spectrum, but propagates inside the Feynman diagrams. Fakeons can be used to…
Large- sigma model on a finite interval: general Dirichlet boundary conditions
Stefano Bolognesi, Sven Bjarke Gudnason, Kenichi Konishi +1
This is the third of the series of articles on the large- two-dimensional sigma model, defined on a finite space interval with Dirichlet boundary conditi…
On Some Universal Features of the Holographic Quantum Complexity of Bulk Singularities
Stefano Bolognesi, Eliezer Rabinovici, Shubho R. Roy
We perform a comparative study of the time dependence of the holographic quantum complexity of some space like singular bulk gravitational backgrounds. This is done by considering…
