Negative Mode Problem of False Vacuum Decay Revisited
Ryusuke Jinno, Ryosuke Sato
We study negative modes around the Coleman-de Luccia bounce solution. The conditions for the appearance of an infinite number of the negative modes do not coincide between Lagrangi…
A hybrid simulation of gravitational wave production in first-order phase transitions
Ryusuke Jinno, Thomas Konstandin, Henrique Rubira
The LISA telescope will provide the first opportunity to probe the scenario of a first-order phase transition happening close to the electroweak scale. By now, it is evident that t…
Occurrence of Tachyonic Preheating in the Mixed Higgs- Model
Minxi He, Ryusuke Jinno, Kohei Kamada +2
It has recently been suggested that at the post-inflationary stage of the mixed Higgs- model of inflation efficient particle production can arise from the tachyonic instabilit…
High-frequency Graviton from Inflaton Oscillation
Yohei Ema, Ryusuke Jinno, Kazunori Nakayama
We point out that there is a high-frequency tail of the stochastic inflationary gravitational wave background that scales as with frequency . This contribution comes…
Deformation of the gravitational wave spectrum by density perturbations
Valerie Domcke, Ryusuke Jinno, Henrique Rubira
We study the effect of primordial scalar curvature perturbations on the propagation of gravitational waves over cosmic distances. We point out that such curvature perturbations def…
