Towards testing the general bounce cosmology with the CMB B-mode auto-bispectrum
Shingo Akama, Giorgio Orlando, Paola C. M. Delgado
It has been shown that a three-point correlation function of tensor perturbations from a bounce model in general relativity with a minimally-coupled scalar field is highly suppress…

Imprints of primordial gravitational waves with non-Bunch-Davies initial states on CMB bispectra
Shingo Akama, Hiroaki W. H. Tahara
It has been shown that both scalar and tensor modes with non-Bunch-Davies initial states can enhance the amplitudes of the primordial bispectra compared to those with the Bunch-Dav…
