Conditions for the existence of a glass phase in disordered systems described by a weak-crystallization Hamiltonian of a general type
Erukhimovich I. Ya. , Dobrynin A. V.
The behavior of disordered systems described by a generalized weak-crystallization Hamiltonian is examined. Systems of this sort contain a region with a phase of the spin-glass type. An expression is derived for the surface which bounds the region. This is a surface of third-order phase transitions. The free energy of the glass phase near the surface is calculated in the leading approximation.
