One-loop mass corrections of interacting string states
Lorenzo Grimaldi, Massimo Bianchi, Maurizio Firrotta
The free string spectrum is highly degenerate, with a degeneracy that grows exponentially with the mass. Turning on a non-vanishing string coupling introduces interactions, r…
Bubbling saddles of the gravitational index
Davide Cassani, Alejandro Ruipérez, Enrico Turetta
We consider the five-dimensional supergravity path integral that computes a supersymmetric index, and uncover a wealth of semiclassical saddles with bubbling topology. These are co…
Visions in Quantum Gravity
Luca Buoninfante, Benjamin Knorr, K. Sravan Kumar +36
To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is cr…
Gravity from Pre-geometry
Andrea Addazi, Salvatore Capozziello, Antonino Marciano +1
The gravitational interaction, as described by the Einstein-Cartan theory, is shown to emerge as the by-product of the spontaneous symmetry breaking of a gauge symmetry in a pre-ge…
Higher-derivative corrections to flavoured BPS black hole thermodynamics and holography
Davide Cassani, Alejandro Ruipérez, Enrico Turetta
A Cardy-like regime of the four-dimensional superconformal index has been shown to be governed by 't Hooft anomalies and to single out a large- saddle carrying the Bekenstein-Ha…
Einstein-Cartan pseudoscalaron inflation
Alessandro Di Marco, Emanuele Orazi, Gianfranco Pradisi
We study a class of early universe cosmological models based on Einstein-Cartan gravity and including a higher derivative term corresponding to a power of the Holst scalar curvatur…
The chaotic emergence of thermalization in highly excited string decays
Maurizio Firrotta
We analyse the most general process of a generic highly excited string that decays into a less excited, yet generic, highly excited string emitting a tachyon. We provide a simple a…
Conformal Metric-Affine Gravities
Gonzalo J. Olmo, Emanuele Orazi, Gianfranco Pradisi
We revisit the gauge symmetry related to integrable projective transformations in metric-affine formalism, identifying the gauge field of the Weyl (conformal) symmetry as a dynamic…
conformal dualities from unoriented chiral quivers
Antonio Amariti, Massimo Bianchi, Marco Fazzi +3
We study various orientifold projections of 4d toric gauge theories, associated with CY singularities known as , with even. We obtain…
OPE coefficients in Argyres-Douglas theories
Agnese Bissi, Francesco Fucito, Andrea Manenti +2
The calculation of physical quantities in certain quantum field theories such as those of the Argyres-Douglas type is notoriously hard, due to the lack of a Lagrangian description.…
Partonic behavior of string scattering amplitudes from holographic QCD models
Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1
We study the emergence of partonic behavior in scattering processes at large Mandelstam's variable from string amplitudes in holographic backgrounds. We generalize the approach…
Metaplectic representation and ordering (in)dependence in Vasiliev's higher spin gravity
David De Filippi, Carlo Iazeolla, Per Sundell
We investigate the formulation of Vasiliev's four-dimensional higher-spin gravity in operator form, without making reference to one specific ordering. More precisely, we make use o…
Strongly Coupled String-inspired Infinite Derivative Non-local Yang-Mills: Diluted Mass Gap
Marco Frasca, Anish Ghoshal
We investigate the non-perturbative regimes in the class of non-Abelian theories that have been proposed as an ultraviolet completion 4-D Quantum Field Theory (QFT) generalizing th…
Spinning-off stringy electro-magnetic memories
Alice Aldi, Massimo Bianchi, Maurizio Firrotta
We extend and generalise the string corrections to the EM memory to the Type I superstring including spin effects. Very much as in the simpler bosonic string context, the relevant…
Light rings of five-dimensional geometries
Massimo Bianchi, Dario Consoli, Alfredo Grillo +1
We study massless geodesics near the photon-spheres of a large family of solutions of Einstein-Maxwell theory in five dimensions, including BHs, naked singularities and smooth hori…
Mass Gap in Infinite Derivative Non-local Higgs: Dyson-Schwinger Approach
Marco Frasca, Anish Ghoshal
We investigate the non-perturbative degrees of freedom in the class of non-local Higgs theories that have been proposed as an ultraviolet completion 4-D Quantum Field Theory (QFT)…
String Memories ... Lost and Regained
Andrea Addazi, Massimo Bianchi, Maurizio Firrotta +1
We discuss stringy corrections to the gravitational wave signal generated in the merging of two black holes. We model the merging with two BPS compact massive objects in the…
Testing Primordial Black Holes as Dark Matter in Supergravity from Gravitational Waves
Yermek Aldabergenov, Andrea Addazi, Sergei V. Ketov
We explore the Gravitational Waves (GW) phenomenology of a simple class of supergravity models that can explain and unify inflation and Primordial Black Holes (PBH) as Dark Matter…
Primordial black holes from modified supergravity
Yermek Aldabergenov, Andrea Addazi, Sergei V. Ketov
The modified supergravity approach is applied to describe a formation of Primordial Black Holes (PBHs) after Starobinsky inflation. Our approach naturally leads to the two-(scalar)…
Holographic Naturalness
Andrea Addazi
The Holographic Naturalness (HN) is a new paradigm towards an explanation of the Cosmological Constant (CC) and the Higgs Hierarchy (HH) in the Universe. Motivated by the Holograph…
Hidden Non-Locality and Self-Superrenormalization of Quantum Gravity
Andrea Addazi
We show that the formation/evaporation of Black Holes (BH) unitarizes quantum gravity at all the orders of the perturbation theory. Non-perturbative quantum effects save the scatte…
Holographic Naturalness and Topological Phase Transitions
Andrea Addazi
We show that our Universe lives in a topological and non-perturbative vacuum state full of a large amount of hidden quantum hairs, the hairons. We will discuss and elaborate on the…
Multi-boundary entanglement in Chern-Simons theory with finite gauge groups
Siddharth Dwivedi, Andrea Addazi, Yang Zhou +1
We study the multi-boundary entanglement structure of the states prepared in (1+1) and (2+1) dimensional Chern-Simons theory with finite discrete gauge group . The states in (1+…
Mass Deformations of Unoriented Quiver Theories
Massimo Bianchi, Davide Bufalini, Salvo Mancani +1
We study the interplay between mass deformations and unoriented projections of super-conformal quiver gauge theories resulting from D3-branes at (toric) Calabi-Yau singularities. W…
