Two different site order parameters are considered to characterize the partial spin-glass behavior of ±J square Ising lattices. On the one hand, q proposed by Edwards and Anderson two decades ago; on the other p, a more drastic parameter introduced recently. Site order parameters depend very...

On the basis of Langevin equation the optimal SUSY field scheme is formulated to describe a non-equilibrium thermodynamic system with quenched disorder and non-ergodicity effects. Thermodynamic and isothermal susceptibilities, memory parameter and irreversible response are determined at...

The Landau Fermi-liquid theory is generalized for a system of fermions with a “color degree of freedom” (quark plasma). It is shown that the phase transition to color ordering state may occur depending on the change in thermodynamic parameters similar to a magnetic phase transition taking...
