How to break the replica symmetry in structural glasses

The variational principle (VP) has been used to capture the metastable states of a glass-forming molecular system without quenched disorder. It has been shown that VP naturally leads to a self-consistent random field Ginzburg-Landau model (RFGLM). In the framework of one-step replica symmetry breaking (1-RSB) the general solution of RFGLM is discussed in the vicinity of the spinodal temperature TA in terms of "hidden" form factors (k), g0(k) and Δ(k). The self-generated disorder spontaneously arises. It is argued that at T < TA the activated dynamics is dominant.
