The effect of primordial temperature fluctuations on the QCD transition
Janne Ignatius
Author(s): J. Ignatius and Dominik J. Schwarz
We analyze a new mechanism for the cosmological QCD first-order phase
transition: inhomogeneous nucleation. The primordial temperature fluctuations
are larger than the tiny temperature interval, in which bubbles would form in
the standard picture of homogeneous nucleation. Thus the bubbles nucleate at
cold spots. We find the typical distance between bubble centers to be a few
meters. This exceeds the estimates from homogeneous nucleation by two orders of
magnitude. The resulting baryon inhomogeneities may affect primordial
nucleosynthesis.
