In R^2-inflation scalaron slow roll is responsible for the inflationary stage, while its oscillations reheat the Universe. We find that the same scalaron decays induced by gravity can also provide the dark matter production and leptogenesis. With R^2-term and three Majorana fermions added to the Standard Model, we arrive at the phenomenologically complete theory capable of simultaneously explaining neutrino oscillations, inflation, reheating, dark matter and baryon asymmetry of the Universe. Besides the seesaw mechanism in neutrino sector, we use only gravity, which solves all the problems by exploiting scalaron.

ACT stands for Awkward Cosmology Theories
Reconciling Starobinsky inflation with ACT data requires fine-tuned higher-curvature scales, stiff reheating with ω_reh>1/3, or negative-energy towers, all hard to motivate from UV completions.

Higgs boson mass and thermal wino dark matter from Starobinsky supergravity with the MSSM
Starobinsky supergravity coupled to the MSSM links the CMB inflationary scale to the Higgs boson mass (~125 GeV) and predicts thermal wino dark matter at ~3 TeV, testable at future colliders and direct detection experiments.

Simulating first-order phase transition during inflation
A GUT-scale first-order phase transition embedded in Starobinsky inflation completes near the end of inflation, and lattice simulations confirm the predicted oscillatory gravitational-wave signal.

Post-inflationary enhancement of adiabatic perturbations in modular cosmology
In modular inflation models, entropic perturbations frozen during inflation are converted into curvature perturbations after inflation, producing an enhanced power spectrum while preserving the spectral index ns.

Tachyonic Encore: A universal shift of inflationary observables
A light axion spectator induces post-inflation tachyonic phases that produce a nearly scale-invariant boost to the curvature power spectrum and alter key inflationary observables in a largely potential-independent manner.

High Frequency Spectrum of Primordial Gravitational Waves
High-frequency primordial gravitational waves extend to higher frequencies due to post-inflation inflaton dynamics, and their detailed spectrum shape can distinguish inflation models.
