Vainshtein Screening in Bimetric Cosmology
Marvin Lüben, Angnis Schmidt-May, Juri Smirnov
We demonstrate that the instabilities in linear cosmological perturbations in bimetric theory are the manifestation of the non-linear Vainshtein mechanism on an FRW background. The…
Dark Matter meets Quantum Gravity
Manuel Reichert, Juri Smirnov
We search for an extension of the Standard Model that contains a viable dark matter candidate and that can be embedded into a fundamental, asymptotically safe, quantum field theory…
The Thermal History of Composite Dark Matter
Nicola Andrea Dondi, Francesco Sannino, Juri Smirnov
We study the thermodynamic history of composite Dark Matter models. We start with classifying the models by means of the symmetries partially protecting the composite Dark Matter d…
TeV-Scale Thermal WIMPs: Unitarity and its Consequences
Juri Smirnov, John F. Beacom
We re-examine unitarity bounds on the annihilation cross section of thermal-WIMP dark matter. For high-mass pointlike dark matter, it is generic to form WIMP bound states, which, t…
Safe Clockwork
Francesco Sannino, Juri Smirnov, Zhi-Wei Wang
In this letter we demonstrate that safe quantum field theories can accommodate the clockwork mechanism upgrading it to a fundamental theory a lá Wilson. Additionally the clockwork…
