A complete analysis of inflation with piecewise quadratic potential
Xinpeng Wang, Xiao-Han Ma, Misao Sasaki
We conduct a thorough study of the comoving curvature perturbation in single-field inflation with two stages, represented by a piecewise quadratic potential, where bo…
Gravitational waves from primordial black hole isocurvature: the effect of non-Gaussianities
Xin-Chen He, Yi-Fu Cai, Xiao-Han Ma +3
Ultra-light primordial black holes (PBHs) with masses can dominate transiently the energy budget of the Universe and reheat the Universe throug…
Extracting parity-violating gravitational waves from projected tidal force tensor in three dimensions
Teppei Okumura, Misao Sasaki
Gravitational waves (GWs) may be produced by various mechanisms in the early universe. In particular, if parity is violated, it may lead to the production of parity-violating GWs.…
New probe of non-Gaussianities with primordial black hole induced gravitational waves
Theodoros Papanikolaou, Xin-Chen He, Xiao-Han Ma +3
We propose a new probe of primordial non-Gaussianities (NGs) through the observation of gravitational waves (GWs) induced by ultra-light () primordial…
