Query: Revisiting the cosmological coherent oscillation   It is often the case that scalar fields are produced in the early Universe in
the form of coherent oscillation. These scalar fields may have huge abundances
and affect the evolution of the Universe. In particular, if the lifetime is
long enough, they may cause cosmological disasters. We revisit the issue of
coherent oscillation of the scalar field when it couples with another
oscillating scalar field, and find a situation that the abundance, or the
amplitude of the oscillation, is significantly reduced by a variant type of the
adiabatic suppression mechanism. As a concrete example, it is applied to the
saxion, a flat direction in the supersymmetric axion model, and we show that
the cosmological saxion problem is solved in a particular setup.
