Beyond monomial -attractors
Laura Iacconi
The paper investigates inflationary α‑attractor models with a binomial (quadratic + quartic) potential, showing that the quartic term can significantly modify the scalar spectral i…
Inflation, Open Universes, and Dark Energy
Anton Chudaykin, Mikhail M. Ivanov, Renata Kallosh +3
The authors analyze how allowing a small negative spatial curvature and/or a time‑varying dark energy equation of state changes the inferred scalar spectral index nₛ from CMB and g…
Inflation in unimodular loop quantum cosmology
Steffen Gielen, Rita B. Neves
The paper investigates inflationary dynamics within unimodular loop quantum cosmology, using a geometrically defined unimodular time and deriving both analytical and numerical solu…
Seesaw Cosmology
Nicolás Bernal, Chee Sheng Fong, Ãscar Zapata
The paper investigates a reheating scenario where the inflaton decays into right‑handed neutrinos that generate light neutrino masses via the type‑I seesaw, leading to a nonstandar…
Searching for signatures of inflationary massive fields in DESI Imaging data and Stage-V galaxy surveys
Walter Riquelme, Santiago Avila, Lucas Pinol +2
The paper studies how massive fields present during inflation could leave detectable signatures in galaxy clustering, using DESI imaging data and forecasting the capability of futu…
New exact bispectrum shapes in multifield inflation
Lucas Pinol
The paper presents an analytical, non‑perturbative calculation of the primordial bispectrum in multifield inflation, deriving integral representations for mixed curvature‑isocurvat…
