The stochastic gravitational-wave background and the inflation to radiation transition in the early universe
2007
Classical and quantum gravity
Preserved Fulltext
Using the differential equations obeyed by the Bogoliubov coefficients, and a simple cosmological model, we calculate features in the gravitational-wave power-spectrum that correspond to different types of transition between the inflationary regime and the radiation dominated era. *
