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.…
Quintessential inflation and nonlinear effects of the tachyonic trap mechanism
Mindaugas Karčiauskas, Stanislav Rusak, Alejandro Saez
With the help of the tachyonic trapping mechanism one can potentially solve a number of problems affecting quintessential inflation models. In this mechanism we introduce a trappin…
The statistically anisotropic curvature perturbation generated by f(ϕ)^2 F^2
David H. Lyth, Mindaugas Karčiauskas
The inflaton might be coupled to a gauge field through a term f^2(ϕ) F_μνF^μν. If f \propto a^{-2} where a(t) is the scale factor, the perturbation δW of the gauge field generates…
The bimetric variational principle for General Relativity
Jose Beltran Jimenez, Alexey Golovnev, Mindaugas Karčiauskas +1
The bimetric variational principle is a subtle reinterpretation of general relativity that assumes the spacetime connection to be generated by an independent metric. Unlike the so…
On the health of a vector field with (R A^2)/6 coupling to gravity
Mindaugas Karčiauskas, David Lyth
The coupling (R A^2)/6 of a vector field to gravity was proposed as a mechanism for generating a primordial magnetic field, and more recently as a mechanism for generating a statis…
