Can anyone explain to me why after chaotic inflation with [itex]V=\frac{1}{2}m^2 \phi^2 [/itex] that the inflaton behaves as;(adsbygoogle = window.adsbygoogle || []).push({});

[itex]\phi=\frac{m_p}{m \sqrt{3\pi}t} \sin(mt)[/itex].

because this doesn't satify the slow roll conditions or the eqn of motion for the inflaton. I have read that it asymptotically approaches ths for large mt but i don't really understand it.

thx
