We describe a way to construct supergravity models with an arbitrary inflaton potential V ({\phi}) and show that all other scalar fields in this class of models can be stabilized at the inflationary trajectory by a proper choice of the K\"ahler potential.

  1. Extending the Dynamical Systems Toolkit: Coupled Fields in Multiscalar Dark Energy

    hep-th 2025-09 unverdicted novelty 7.0 of 10

    New dynamical systems variables for coupled axion-saxion fields yield a general non-geodesicity expression at fixed points and identify genuinely non-geodesic attractors under exponential couplings.

  2. Gravitational waves from self-resonance during reheating with a quantum-corrected inflaton potential

    hep-ph 2026-07 conditional novelty 6.0 of 10

    A Coleman-Weinberg correction that cancels the inflaton's quadratic term at the potential minimum triggers quartic self-resonance and a peaked GW background at 10^8-10^10 Hz; a negative quadratic term instead gives a ...

  3. Kinetically Modified Palatini Inflation Meets ACT Data

    hep-ph 2025-05 conditional novelty 6.0 of 10

    Palatini chaotic inflation with kinetic mixing f_K = f_R^m can shift the predicted spectral index up to the ACT DR6 value n_s = 0.974 while keeping r below current bounds.

  4. Gravitational Dark Matter Production in Supergravity $\alpha$-Attractor Inflation

    hep-ph 2024-11 conditional novelty 6.0 of 10

    Supergravity corrections in α-attractor inflation suppress gravitational dark matter production and shift the required reheating temperature to 10^3-10^7 GeV.

  5. Starobinsky Inflation with T-Model Kaehler Geometries

    hep-ph 2025-02 conditional novelty 5.0 of 10

    Starobinsky-like inflation is embedded in supergravity via T-model Kähler potentials, yielding ns in the range 0.961 to 0.969 and a tensor-to-scalar ratio that rises with Kähler curvature.

  6. Noncanonical Approaches To Inflation

    gr-qc 2019-06 unverdicted novelty 3.0 of 10

    A review thesis covering Mukhanov parametrization, general scalar-tensor theories, and new slow-roll techniques for canonical and noncanonical inflation observables.
