Brazovskii fluctuation-induced first-order transition
= Brazovskii fluctuation-induced first-order transition
{c}
In a self-consistent Gaussian treatment, fluctuations near the soft-mode sphere generate a positive <mass> shift that diverges as the renormalized <mass> approaches zero. The disordered phase therefore remains locally stable until its free <energy> crosses that of a finite-amplitude modulated phase, producing a first-order transition.
