Perturbative quantum corrections to primordial power spectra are important for testing the robustness and the regime of validity of inflation as an effective field theory. Although this has been done extensively for the density power spectrum (and, to some extent, for the tensor spectrum) using loop corrections, we do so in an open quantum system approach to the problem. Specifically, we calculate the first order corrections to the primordial gravitational wave spectrum due to (cubic) tensor interactions alone. We show that our results match expectations from standard loop corrections only in the strict Markovian limit, and therefore, establish a systematic way to relax this approximation in the future, as is generally necessary for gravitational systems.

  1. Mutual information as a measure of renormalizability

    hep-th 2025-11 conditional novelty 6.0 of 10

    The logarithmic slope of momentum-space mutual information with mode separation classifies λφⁿ theories into super-renormalizable, marginal, and non-renormalizable.

  2. Inflationary Decoherence from the Gravitational Floor

    gr-qc 2025-09 conditional novelty 6.0 of 10

    Gravitational self-interactions alone decohere super-Hubble inflationary fluctuations with purity loss growing as (aH/k)^5, faster than the a^3 growth of earlier calculations.

  3. Probing the self-coherence of primordial quantum fluctuations with complexity

    hep-th 2025-02 conditional novelty 5.0 of 10

    Complexity of formation, unlike complexity of purification, shows distinct and timescale-matching signatures of both decoherence and recoherence in a Gaussian two-field de Sitter model.
