“…This "duality" is exhibited using the covariant Maxwell-Weyl form of the Einstein field equations (see section II and e.g. [8]), and is partially hidden in the Bardeen formalism [18]. This demonstration of gravitational wave amplification should be considered in the light of the controversy surrounding tensor amplification during instantaneous phase transitions.…”

The gravitational wave equations form a parametric resonance system during oscillatory reheating after inflation, when cast in terms of the electric and magnetic parts of the Weyl tensor. This is in direct analogy with preheating. For chaotic inflation with a quadratic potential, this analogy is exact. The resulting amplification of the gravitational wave spectrum begins in the broad-resonance regime for chaotic inflation but quickly moves towards narrow resonance. This increases the amplitude and breaks the scale invariance of the tensor spectrum generated during inflation, an effect which may be detectable. The parametric amplification is absent, however, in first-order phase transition models and ''warm'' inflationary models with continuous entropy production.

“…m φ ≫ Θ. However, the oscillations of the expansion rate should also be included in a full description 4 [18] which will act as an additional source of resonance. This will be important in obtaining the tensor spectrum from oscillating cold dark matter (CDM) relics like the invisible axion [31].…”
