Bridging Superfluid and Nonminimally Coupled BEC Dark Matter through RAQUAL
Stefano Liberati, Valentin Pomakov, Samuele Silveravalle
Motivated by their common condensed-matter inspiration and their shared aim of reconciling MOND-like phenomenology on galactic scales with particle dark matter on larger scales, we…
Cosmology with a Non-minimally Coupled Dark Matter Fluid II. Cosmological Perturbations
Samuele Silveravalle, Andrea Lapi, Francesco Benetti +1
We extend our study of a cosmological scenario in which dark matter is non-minimally coupled to gravity at the fluid level. In previous work, we showed that this interaction can dr…
Freezing lakes as analogue models of CDM cosmology and beyond
Lorens F. Niehof, Ananya Venkatasubramanian, Federico Toschi +1
We extend previous conduction-based analogies between ice growth in a lake and cosmological expansion by incorporating buoyancy-driven heat transport. Reformulating the Stefan prob…
Cosmology with a Non-minimally Coupled Dark Matter Fluid I. Background Evolution
Samuele Silveravalle, Andrea Lapi, Francesco Benetti +1
We explore a cosmological model in which dark matter is non-minimally coupled to gravity at the fluid level. While typically subdominant compared to Standard Model forces, such cou…
A Relativistic Tensorial Model for Fractional Interaction between Dark Matter and Gravity
Francesco Benetti, Andrea Lapi, Samuele Silveravalle +5
In a series of recent papers it was shown that several aspects of Dark Matter (DM) phenomenology, such as the velocity profiles of individual dwarfs and spiral galaxies, the scalin…
Ultra-compact Objects of Non-minimally Coupled Dark Matter
Francesco Benetti, Andrea Lapi, Samuele Silveravalle +1
In the framework of a collisionless dark matter fluid which is non-minimally coupled to gravity, we investigate the existence and properties of static, spherically symmetric soluti…
