A brief review of the works of the authors on generalized spin glass models is given. The problem of the dependence of transition
scenario on different factors is discussed. A classification of spin glasses behavior as depending on symmetry characteristics
of systems is proposed. 相似文献

We propose a model for describing the low-temperature transition to the orientational glass state in solid molecular C60 in the framework of a theory similar to spin glass theory. We find a replica symmetric solution and also break the replica
symmetry. The obtained results agree with experimental data on the partial retention of the orientational long-range order
in the glass phase and on the presence of a broad maximum on the curve corresponding to the temperature dependence of the
orientational part of the heat capacity.

We review our papers devoted to theoretical studies of the behavior of mixtures of ultracold atoms in optomagnetic traps.
We discuss the phase separation and vortexlike states in mixtures of bosonic atoms and also the stability and vortexlike states
in Bose-Fermi mixtures with attraction between the components.

We review the results related to the ultrametricity notion in glasses. We present the proof of the ultrametricity of the replica space for an arbitrary spin glass model with reflection symmetry. We solve the problem of describing the dynamics of a system with an ultrametric state space using the Keldysh functional method for nonequilibrium dynamics in which the quasinonergodicity of the system is taken into account by introducing a hierarchical spectrum of relaxation times. 相似文献

We propose an approximation of a direct correlation function corresponding to the linearization with respect to ?β?(r) of a generalized mean spherical approximation for a hard-core multi-Yukawa system of particles. We use the results to study the behavior of maximums of thermodynamic response functions in the supercritical region of a fluid with a two-term Yukawa potential imitating the Lennard-Jones potential. 相似文献
