Hydrodynamics of Filtered Dark Matter: A Two-Component Approach
Juntaro Wada
We study the hydrodynamics of the Filtered Dark Matter (Filtered DM) scenario during a first-order phase transition (FOPT). In this scenario, the bubble wall is highly reflective o…

Asymmetric Dark Matter from Low-Scale Spontaneous Leptogenesis
Hiroki Takahashi, Juntaro Wada
We investigate a novel type of asymmetric dark matter (ADM) model in which the dark matter asymmetry and the baryon asymmetry in our universe (BAU) are produced simultaneously via…

Gauge coupling jump and small instantons from a large non-minimal coupling
Juntaro Wada, Wen Yin
If a scalar field couples to the Ricci scalar with a large non-minimal coupling, the Standard Model coupling parameters can differ above and below an intermediate field range of th…
