High-frequency oscillations of Newton’s constant induced by inflation
High-frequency oscillations of Newton’s constant induced by inflation
We examine the possibility that an epoch of inflationary expansion induces high-frequency oscillations of Newton's constant G. The effect occurs because inflation can shift the expectation value of a nonminimally coupled, Brans-Dicke-like field away from the minimum of its effective potential. At some time after inflation ends, the field begins …
