DSWIM adds a Hubble-scaled deterministic correlation matrix evolution to SWIM that preserves the primordial curvature power spectrum exactly while improving numerical conditioning and resolving stochastic-deterministic discrepancies.
In perturbatively moduli-stabilized brane-antibrane inflation, a modest fraction of annihilation energy into visible open strings can trigger a Hagedorn phase that suppresses ΔN_eff when the SM throat string scale is comparable or lower.
Non-Bunch-Davies initial conditions substantially improve the fit of various single-field slow-roll inflation models to updated n_s-r constraints from ACT DR6 combined with Planck, DESI, and BICEP/Keck data.
Multi-field fibre inflation in perturbative LVS uses collective dynamics of several moduli to achieve viable cosmology with sub-Planckian individual field ranges given by total range divided by sqrt(n).
