An Introduction to Effective Field Theories
Riccardo Penco
These notes are an overview of effective field theory (EFT) methods. I discuss toy model EFTs, chiral perturbation theory, Fermi liquid theory, and non-relativistic QED, and use th…
Extreme Mass Ratio Inspirals with Scalar Hair
Adrien Kuntz, Riccardo Penco, Federico Piazza
Stellar mass objects orbiting around supermassive black holes are primary targets for future gravitational wave detectors like LISA. However, in theories beyond general relativity,…
Baryon-Interacting Dark Matter: heating dark matter and the emergence of galaxy scaling relations
Benoit Famaey, Justin Khoury, Riccardo Penco +1
The empirical scaling relations observed in disk galaxies remain challenging for models of galaxy formation. The most striking among these is the Mass Discrepancy-Acceleration Rela…
A Universal Relation Between Corrections to Entropy and Extremality
Garrett Goon, Riccardo Penco
Perturbative corrections to General Relativity alter the expressions for both the entropy of black holes and their extremality bounds. We prove a universal relation between the lea…
Gauged Galileons
Sebastian Garcia-Saenz, Jonghee Kang, Riccardo Penco
We discuss the gauging of non-linearly realized symmetries as a method to systematically construct spontaneously broken gauge theories. We focus in particular on galileon fields an…
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…
