Quantum limit to transparency
Angelo Esposito, Alberto Nicolis, Federico Piazza
We argue that no material can be made completely transparent to light as long as it has a nontrivial index of refraction. The quantum decay of photons into phonons is an ineliminab…
Effective Field Theories for Material Media
Angelo Esposito, Alberto Nicolis, Riccardo Penco
We review recent progress in understanding certain aspects of condensed matter systems from a high energy theory perspective. We discuss effective field theories that describe coll…
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…
