General Analytical Conditions for Inflaton Fragmentation: Quick and Easy Tests for its Occurrence
Jinsu Kim, John McDonald
Understanding the physics of inflaton condensate fragmentation in the early Universe is crucial as the existence of fragments in the form of non-topological solitons (oscillons or…
Primordial blackholes from Gauss-Bonnet-corrected single field inflation
Shinsuke Kawai, Jinsu Kim
Primordial blackholes formed in the early Universe via gravitational collapse of over-dense regions may contribute a significant amount to the present dark matter relic density. In…
CMB from a Gauss-Bonnet-induced de Sitter fixed point
Shinsuke Kawai, Jinsu Kim
In the gravitational effective theories including higher curvature terms, cosmological solutions can have nontrivial de Sitter fixed points. We study phenomenological implications…
A multi-component SIMP model with
Soo-Min Choi, Jinsu Kim, Pyungwon Ko +1
Multi-component dark matter scenarios are studied in the model with dark gauge symmetry that is broken into its product subgroup á la Krauss-Wilczek mecha…
Characterization of a flux-driven Josephson parametric amplifier with near quantum-limited added noise for axion search experiments
Çağlar Kutlu, Arjan F. van Loo, Sergey V. Uchaikin +7
The axion, a hypothetical elementary pseudoscalar, is expected to solve the strong CP problem of QCD and is also a promising candidate for dark matter. The most sensitive axion sea…
