Ap. Saiko et al., NONSTABILITY AND HYSTERESIS IN SCALAR PHI -4-MODEL WITH THE ASYMMETRIC TWOPIT POTENTIAL, Doklady Akademii nauk BSSR, 37(5), 1993, pp. 38-41
The microscopic model of anharmonically unstable lattice is proposed.
In the framework of the model the state equation, free energy and dyna
mical susceptibility are determined.
