Abstract:
We quantize the gravitational wave which arises from quantum fluctuations in the inflationary universe and compute its time evolution using a simple model of the cosmological evolution. As a result, we obtain the power spectrum of the background gravitational wave and calculate the behavior of the squeezed parameters.
