Production of fluctuations in the early universe by the quark-nucleon phase transition
Abstract
A model of the early universe is proposed which initially contains a zero-temperature quark phase. The entropy of the cosmic background radiation is generated by an irreversible transition to the usual radiation-dominated nucleon gas. At recombination time the model has density fluctuations with a characteristic mass of 106 solar masses. © 1979 The American Physical Society.
