Exact numerical simulations of parametric resonance in φ⁴ preheating reveal coupling-dependent behaviors: short-wavelength modes saturate while long-wavelength modes grow gradually in the weak regime, with stochastic and staircase-like production appearing at stronger couplings, differing from prior
Backreaction in semiclassical scalar QED in 1+1D avoids instabilities and produces over-screening at high external charges.
Nonlinear dynamics of a U(1)-breaking complex scalar field generates the observed baryon asymmetry from symmetric initial conditions, with late-time charge density scaling as t^{-3/2} via dynamical freeze-in.
Single-field slow-roll inflation achieves ns=1 by ending inflation suddenly via a large step in the potential.
A perturbatively and tensorially structured quantum-deformed conformal metric yields analytical expressions for inflationary observables including quantum corrections to power spectra, spectral indices, and tensor-to-scalar ratio while recovering classical limits.
In this two-field completion, trajectories connected to the Starobinsky solution keep entropy modes suppressed so that curvature and tensor perturbations remain effectively single-field Starobinsky-like.
Non-minimal effective scalar-tensor gravity supports early-universe bounce, inflation, and genesis while producing two Hubble values that could resolve the Hubble tension.
Updated Planck CMB measurements give ns = 0.9649 ± 0.0042, r < 0.056, confirm flatness at 0.4 percent, and show no evidence for scale-dependent features or non-slow-roll dynamics in the inflaton potential.
Dyson-Schwinger methods applied to gravity theories produce conformally flat metrics and a sequence of cosmological phase transitions from conformal symmetry breaking that non-minimal scalar couplings can suppress.
