Cosmology of fractional gravity
Iván Salvador-García, Gianluca Calcagni
This is a first study of the cosmology of classical fractional gravity, a nonlocal proposal endowed with self-adjoint fractional d'Alembertian operators which serves as the basis f…
Hawking area law in quantum gravity
Gianluca Calcagni
We show that the LIGO--Virgo--KAGRA verification of Hawking area law carries profound consequences for quantum gravity if such a law is postulated to hold exactly. The observed mer…
Perturbative unitarity of fractional field theories and gravity
Gianluca Calcagni, Fabio Briscese
Motivated by quantum gravity on spacetimes with multi-scale geometry, we analyze quantum field theories with a self-adjoint fractional power of the d'Alembertian i…
Fractal universe and quantum gravity made simple
Fabio Briscese, Gianluca Calcagni
Quantum field theory (QFT) on fractal spacetimes is a program aiming at quantizing the gravitational interaction consistently at all energy scales thanks to an intrinsically or dyn…
Probing Cosmic Expansion and Early Universe with Einstein Telescope
Angelo Ricciardone, Mairi Sakellariadou, Archisman Ghosh +52
Over the next two decades, gravitational-wave (GW) observations are expected to evolve from a discovery-driven endeavour into a precision tool for astrophysics, cosmology, and fund…
LISA as a probe of pre-big-bang physics: a nested sampling analysis
Xoán Vilas Currás, Gianluca Calcagni
Using a nested sampling analysis, we study the gravitational-wave background (GWB) predicted by the Gasperini--Veneziano model of pre-big-bang cosmology, both in its most recent mi…
