Query: Interplay of friction and noise and enhancement of disoriented chiral
  condensate   Using the Langevin equation for the linear $\sigma$ model, we have
investigated the effect of friction and noise on the possible disoriented
chiral condensate formation. Friction and noise are supposed to suppress
longwavelength oscillations and growth of disoriented chiral condensate
domains. Details simulation shows that for heavy ion collisions, interplay of
friction and noise occur in such a manner that formation of disoriented chiral
condensate domains are enhanced.
