On the rate of gravitational inflaton decay via gauge trace anomaly
gravitational inflaton decay trace anomaly
2010/12/21
We analyze decay processes of the inflaton field, , during the coherent oscillation phase after inflation in f( )R gravity. It is inevitable that the inflaton decays grav-itationally into gauge field...
On the Trace Anomaly and the Energy-Momentum Conservation of Quantum Fields at D=2 in Classical Curved Backgrounds
the Energy-Momentum Conservation Quantum Fields Classical Curved Backgrounds
2010/10/21
We study the conformal symmetry and the energy-momentum conservation of scalar field interacting with a curved background at D = 2. We avoid to incorporate the metric determinant into the measure of t...
