Abstract
The variational principle (VP) has been used to capture the metastable stat es of a glass-forming molecular system without quenched disorder. It has be en shown that VP naturally leads to a self-consistent random field Ginzburg -Landau model (RFGLM). In the framework of one-step replica symmetry breaki ng (1-RSB) the general solution of RFGLM is discussed in the vicinity of th e spinodal temperature TA in terms of "hidden" form factors (g) over tilde( k), g(0)(k) and Delta(k). The self-generated disorder spontaneously arises. It is argued that at T < T-A the activated dynamics is dominant.
