Insights into the highest natural scale: Finite naturalness challenges inflationary dynamics
Pier Giuseppe Catinari, Loris Del Grosso, Luca Di Giovanni +1
We apply the criterion of finite naturalness to the limiting case of a generic heavy sector decoupled from the Standard Model. The sole and unavoidable exception to this decoupling…

Hunting axion dark matter with anti-ferromagnets: a case study with nickel oxide
Pier Giuseppe Catinari, Angelo Esposito, Shashin Pavaskar
We show that nickel oxide, which is already a very promising target to look for sub-MeV dark matter scattering, can be employed to hunt axion dark matter, with masses in the meV ra…

An EFT for anisotropic anti-ferromagnets: gapped Goldstones, pseudo-Goldstones, and phase transitions
Pier Giuseppe Catinari, Angelo Esposito, Shashin Pavaskar
We build and discuss a low energy effective field theory for anisotropic anti-ferromagnets in presence of an external magnetic field. Such an effective theory is simple yet rich, a…
