Gapped dilatons in scale invariant superfluids
Riccardo Argurio, Carlos Hoyos, Daniele Musso +1
We study a paradigmatic model in field theory where a global and scale symmetries are jointly and spontaneously broken. At zero density the model has a non-compact flat dire…

Phonon and Shifton from a Real Modulated Scalar
Daniele Musso, Daniel Naegels
We study a massive real scalar field that breaks translation symmetry dynamically. Higher-gradient terms favour modulated configurations and neither finite density nor temperature…

Are there Goldstone bosons in ?
Riccardo Argurio, Daniel Naegels, Antoine Pasternak
We study the viability of spontaneous breaking of continuous symmetries in theories with Lifshitz scaling, according to the number of space-time dimensions and the dynamical sc…
