Hamiltonian formalism for cosmological perturbations: the separate-universe approach
Danilo Artigas, Julien Grain, Vincent Vennin
The separate-universe approach provides an effective description of cosmological perturbations at large scales, where the universe can be described by an ensemble of independent, l…
Four-mode squeezed states: two-field quantum systems and the symplectic group
Thomas Colas, Julien Grain, Vincent Vennin
We construct the four-mode squeezed states and study their physical properties. These states describe two linearly-coupled quantum scalar fields, which makes them physically releva…
Overview of the Medium and High Frequency Telescopes of the LiteBIRD satellite mission
L. Montier, B. Mot, P. de Bernardis +232
LiteBIRD is a JAXA-led Strategic Large-Class mission designed to search for the existence of the primordial gravitational waves produced during the inflationary phase of the Univer…
LiteBIRD: JAXA's new strategic L-class mission for all-sky surveys of cosmic microwave background polarization
M. Hazumi, P. A. R. Ade, A. Adler +233
LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection, is a space mission for primordial cosmology and…
Concept Design of Low Frequency Telescope for CMB B-mode Polarization satellite LiteBIRD
Y. Sekimoto, P. A. R. Ade, A. Adler +232
LiteBIRD has been selected as JAXA's strategic large mission in the 2020s, to observe the cosmic microwave background (CMB) -mode polarization over the full sky at large angular…
