Boltzmann equation and its cosmological applications

Seishi Enomoto, Yu-Hang Su, Man-Zhu Zheng +1

We review the derivation of the Boltzmann equation and its cosmological applications in this paper. The derivation of the Boltzmann equation, especially the collision term, is disc…

QCD preheating: New frontier of baryogenesis

Xin-Ru Wang, Jin-Yang Li, Seishi Enomoto +2

We find that QCD can create the cosmological matter abundance via out-of-equilibrium processes during the QCD phase transition, that is what we call the QCD preheating, where the d…

The Exact WKB analysis and the Stokes phenomena of the Unruh effect and Hawking radiation

Seishi Enomoto, Tomohiro Matsuda

The physical observables of quantum theory can be described by perturbation theory, which is often given by diverging power series. This divergence is connected to the existence of…

The Exact WKB analysis for asymmetric scalar preheating

Seishi Enomoto, Tomohiro Matsuda

Using the exact WKB analysis of the higher-order differential equations, we analyze the asymmetry in dynamical particle production of a complex scalar field. The solution requires…

The Exact WKB and the Landau-Zener transition for asymmetry in cosmological particle production

Seishi Enomoto, Tomohiro Matsuda

Cosmological particle production by a time-dependent scalar field is common in cosmology. We focus on the mechanism of asymmetry production when interaction explicitly violates sym…

The exact WKB for cosmological particle production

Seishi Enomoto, Tomohiro Matsuda

The Bogoliubov transformation in cosmological particle production can be explained by the Stokes phenomena of the corresponding ordinary differential equation. The calculation beco…
