Leggett-Garg Inequalities for Squeezed States
Jerome Martin, Vincent Vennin
Temporal Bell inequalities, or Leggett-Garg Inequalities (LGI), are studied for continuous-variable systems placed in a squeezed state. The importance of those systems lies in thei…
Squeezed Bispectrum in the Formalism: Local Observer Effect in Field Space
Yuichiro Tada, Vincent Vennin
The prospects of future galaxy surveys for non-Gaussianity measurements call for the development of robust techniques for computing the bispectrum of primordial cosmological pertur…
Exploring Cosmic Origins with CORE: Extragalactic sources in Cosmic Microwave Background maps
G. De Zotti, J. Gonzalez-Nuevo, M. Lopez-Caniego +121
We discuss the potential of a next generation space-borne Cosmic Microwave Background (CMB) experiment for studies of extragalactic sources. Our analysis has particular bearing on…
Shortcomings of New Parametrizations of Inflation
Jerome Martin, Christophe Ringeval, Vincent Vennin
In the hope of avoiding model dependence of the cosmological observables, phenomenological parametrizations of Cosmic Inflation have recently been proposed. Typically, they are exp…
Inflation Model Selection meets Dark Radiation
Thomas Tram, Robert Vallance, Vincent Vennin
We investigate how inflation model selection is affected by the presence of additional free-streaming relativistic degrees of freedom, i.e. dark radiation. We perform a full Bayesi…
Constraining Curvatonic Reheating
Robert J. Hardwick, Vincent Vennin, Kazuya Koyama +1
We derive the first systematic observational constraints on reheating in models of inflation where an additional light scalar field contributes to primordial density perturbations…
