Cross-Correlations of Metric and Monopole Perturbations from Holographic Cosmology
Matheus Cravo, Juliana Z. Finotti, Horatiu Nastase
In this paper, we present the 1-loop calculation of the three-point function of the stress-energy tensor and two insertions of global currents, using…
3d QFT IR divergences as UV divergences in 4d Holographic Cosmology
Matheus Cravo, Horatiu Nastase
In this paper we consider IR divergences in a 3d toy model field theory for 4d holographic cosmology, and we analyze them by introducing a mass term in a way that preserves a certa…
Holographic Cosmology -point function map from the Wavefunction of the Universe
Matheus Cravo, Horatiu Nastase
In this note we show explicitly that, applying an extension of Maldacena's map for the wavefunction of the Universe from de Sitter inflation to holographic cosmology, w…
3-point function of currents for holographic cosmology and monopole non-Gaussianities
Matheus Cravo, Horatiu Nastase
In this paper we present the calculation of the three-point function in momentum space of currents for a global symmetry, in a three-dimensional toy model within phenomenol…
