Fractional soft limits
Tomáš Brauner, Angelo Esposito, Riccardo Penco
It is a common lore that the amplitude for a scattering process involving one soft Nambu--Goldstone boson should scale like an integer power of the soft momentum. We revisit this e…
Effective Field Theory for Acoustic and Pseudo-Acoustic Phonons in Solids
Angelo Esposito, Emma Geoffray, Tom Melia
We present a relativistic effective field theory for the interaction between acoustic and gapped phonons in the limit of a small gap. We show that, while the former are the Goldsto…
Gapped Goldstones at the cut-off scale: a non-relativistic EFT
Gabriel Cuomo, Angelo Esposito, Emanuele Gendy +3
At finite density, the spontaneous breakdown of an internal non-Abelian symmetry dictates, along with gapless modes, modes whose gap is fixed by the algebra and proportional to the…
Solidity without inhomogeneity: Perfectly homogeneous, weakly coupled, UV-complete solids
Angelo Esposito, Rafael Krichevsky, Alberto Nicolis
Solid-like behavior at low energies and long distances is usually associated with the spontaneous breaking of spatial translations at microscopic scales, as in the case of a lattic…
Conformal solids and holography
A. Esposito, S. Garcia-Saenz, A. Nicolis +1
We argue that a magnetic monopole in an asymptotically AdS space-time is dual to a -dimensional strongly coupled system in a solid state. In light of this, it would be r…
Vortex precession in trapped superfluids from effective field theory
Angelo Esposito, Rafael Krichevsky, Alberto Nicolis
We apply a recently developed effective string theory for vortex lines to the case of two-dimensional trapped superfluids. We do not assume a perturbative microscopic description f…
