Bounds on nonlinear electrodynamics via resummed relative entropy
Pietro Conzinu, Daiki Ueda
We investigate nonlinear electrodynamic effective field theories (EFTs) through the relative entropy evaluated in suitable background electromagnetic fields. In this setup, the rel…
Bounds on nonlinear effective field theories via resurgent relative entropy
Pietro Conzinu, Daiki Ueda
We study a class of nonlinear effective field theories (EFTs) in which relative entropy organizes an infinite tower of higher-dimensional operators with factorially growing coeffic…
Constraints on the Pre-Big Bang scenario from a cosmological interpretation of the NANOGrav data
P. Conzinu, G. Fanizza, M. Gasperini +3
We discuss a recently proposed fit of the 15-year data set obtained from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) in terms of a relic stochastic…
On the stability of string-hole gas
Denis Bitnaya, Pietro Conzinu, Giovanni Marozzi
Focusing on a string-hole gas within the pre-big bang scenario, we study the stability of its solutions in the phase space. We firstly extend the analysis present in the literature…
From the string vacuum to FLRW or de Sitter via corrections
P. Conzinu, G. Fanizza, M. Gasperini +3
We first make more precise a recent "Hamiltonian" reformulation of the Hohm-Zwiebach approach to the tree-level, -invariant string cosmology equations at all orders in the…
