Platonic solids back in the sky: Icosahedral inflation
Jonghee Kang, Alberto Nicolis
We generalize the model of solid inflation to an anisotropic cosmic solid. Barring fine tunings, the observed isotropy of the cosmological background and of the scalar two-point fu…
Effective string theory for vortex lines in fluids and superfluids
Bart Horn, Alberto Nicolis, Riccardo Penco
We discuss the effective string theory of vortex lines in ordinary fluids and low-temperature superfluids, by describing the bulk fluid flow in terms of a two-form field to which v…
Zoology of condensed matter: Framids, ordinary stuff, extra-ordinary stuff
Alberto Nicolis, Riccardo Penco, Federico Piazza +1
We classify condensed matter systems in terms of the spacetime symmetries they spontaneously break. In particular, we characterize condensed matter itself as any state in a Poincar…
