The silent dark sector: a field-theory approach to unified dark fluids with vanishing speed of sound
Javier de Cruz Pérez, DarÃo Jaramillo-Garrido, Antonio L. Maroto +1
We introduce a novel class of field-theory models that provide a unified description of the dark sector as a single perfect fluid with vanishing sound speed. These models also admi…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
CDM from broken diffeomorphisms
Javier de Cruz Pérez, Antonio L. Maroto
We present a simple field theory model with reduced invariance under diffeomorphisms whose energy-momentum tensor is identical to the sum of pressureless irrotational matter and a…
Linking structure and optical properties of plasmonic nanoparticles on tunable spherical surfaces
Francesco Brasili, Angela Capocefalo, Giovanni Del Monte +8
The complexation of plasmonic nanoparticles (NPs) and thermoresponsive microgels is widely exploited for applications, but a microscopic description of the mechanisms governing the…
