Toller matrices and the Feynman in spinfoams
Eugenio Bianchi, Chaosong Chen, Mauricio Gamonal
We study the analytic properties and three equivalent representations of the Toller matrices which appear in the causal formulation of spinfoam transition amplitudes fo…
Causal spinfoam vertex for 4d Lorentzian quantum gravity
Eugenio Bianchi, Chaosong Chen, Mauricio Gamonal
We introduce a new causal spinfoam vertex for d Lorentzian quantum gravity. The causal data are encoded in Toller -matrices, which add to Wigner -matrices $T^{(+)}+T^{(-)}…
Precision predictions of Starobinsky inflation with self-consistent Weyl-squared corrections
Eugenio Bianchi, Mauricio Gamonal
Starobinsky's inflation provides a compelling one-parameter inflationary model that is supported by current cosmological observations. However, at the same order in spacet…
Squeezed vacua and primordial features in effective theories of inflation at N2LO
Eugenio Bianchi, Mauricio Gamonal
A finite duration of cosmic inflation can result in features in the pr…
Primordial power spectrum at N3LO in effective theories of inflation
Eugenio Bianchi, Mauricio Gamonal
We develop a systematic framework to compute the primordial power spectrum up to next-to-next-to-next to leading order (N3LO) in the Hubble-flow parameters for a large class of eff…
Slow-roll inflation in f(R,T) gravity and a modified Starobinsky-like inflationary model
Mauricio Gamonal
In this work, we studied the slow-roll approximation of cosmic inflation within the context of gravity, where is the scalar curvature, and is the trace of the ener…
A nontrivial footprint of standard cosmology in the future observations of low-frequency gravitational waves
Jorge Alfaro, Mauricio Gamonal
Recent research show that the cosmological components of the Universe should influence on the propagation of Gravitational Waves (GWs) and even it has been proposed a new way to me…
