Description
We calculate the dissipation rate of a coherent scalar field oscillation in a thermal environment such as in the late reheating stage after inflation using nonequilibrium quantum field theory. It is shown that the dissipation rate is nonvanishing even when the decay products have a larger thermal mass than the oscillating scalar field, and its cosmological implications are discussed
