Effects of white noise on parametric resonance in $\lambda {\varphi }^4$ theory

Masamichi Ishihara

We investigate the effects of white noise on parametric resonance in $\lambda {\varphi }^4$ theory. The potential $V(\varphi )$ in this study is $1/2m^2{\varphi }^2+1/3g{\varphi }^3+1/4\lambda {\varphi }^4$. An M…
