The Gravitational-Wave Physics II: Progress
Ligong Bian, Rong-Gen Cai, Shuo Cao +15
It has been a half-decade since the first direct detection of gravitational waves, which signifies the coming of the era of the gravitational-wave astronomy and gravitational-wave…
Induced gravitational waves as a probe of thermal history of the universe
Guillem Domènech, Shi Pi, Misao Sasaki
The scalar perturbation induced gravitational waves are a probe of the primordial density perturbation spectrum on small scales. In this paper, we show that they can also probe the…
Gravitational Waves Induced by Scalar Perturbations with a Lognormal Peak
Shi Pi, Misao Sasaki
We study the stochastic gravitational wave (GW) background induced by the primordial scalar perturbation with the spectrum having a lognormal peak of width at . We deriv…
Primordial Tensor Perturbation in Double Inflationary Scenario with a Break
Shi Pi, Misao Sasaki, Ying-li Zhang
We study the primordial tensor perturbation produced from the double inflationary scenario with an intermediate break stage. Because of the transitions, the power spectrum deviates…
Oscillating scalar fields in extended quintessence
Dan Li, Shi Pi, Robert J. Scherrer
We study a rapidly-oscillating scalar field with potential nonminally coupled to the Ricci scalar via a term of the form in the action. In…
