Gravitational waves from self-resonance during reheating with a quantum-corrected inflaton potential
Tomoya Inada, Noel Jonathan Jobu, Kenji Nishiwaki +2
We investigate how localized quantum corrections to the inflaton potential affect preheating dynamics and the resulting stochastic gravitational wave (GW) spectrum. When these corr…

Perturbative unitarity bounds on field-space curvature in de Sitter spacetime: purity vs scattering amplitude
Qianhang Cai, Tomoya Inada, Masataka Ishikawa +2
We study perturbative unitarity bounds on the field-space curvature in de Sitter spacetime, using the momentum-space entanglement approach recently proposed by Duaso Pueyo, Goodhew…
