Abstract

We investigated a model of harmonically coupled oscillators placed in an asymmetric double-well potential of the ψ4, ψ3 type. This model can be a good candidate for the description of pyroelectric crystalline materials. According to the model the system is in a nonergodic state in a certain range of temperatures.
