Loop Blow-up Inflation: An Overview

Sukŗti Bansal

This proceedings contribution provides an overview of Loop Blow-up Inflation and updates its observational predictions and their comparison with the latest CMB and BAO data. It is…

Running Love Numbers of Charged Black Holes

Sergio Barbosa, Sylvain Fichet, Lucas de Souza

Loops of virtual particles from the vacuum of quantum field theory (QFT) render black holes tidally deformable. We compute the static tidal response of unspinning charged black hol…

Extending Weinberg's EFT: effective scalar-tensor theories up to sixth order

Eugeny Babichev, Sukŗti Bansal, Maria Mylova +1

We present a systematic construction of the six-derivative effective scalar-tensor theories, extending the four-derivative framework previously developed by Steven Weinberg. The on…

Higher spin Lagrangians from higher derivative diffeomorphisms

Will Barker, Dario Francia, Carlo Marzo +1

The covariant description of massless particles of arbitrary spin typically employs symmetric tensors of rank and rests on a local symmetry carried by symmetric tensor paramete…

Free-field construction of Carrollian -algebras

Stefan Fredenhagen, Lucas Hörl

We study Carrollian contractions of -algebras from a free-field perspective. Using a contraction of the Miura transformation, we obtain explicit free-field realizations of the…
