Abstract:
Thermodynamics of the 1D ferroelectric model with proton tunneling has been reduced to the calculation of the grand partition function of the 1D Ising model of spin $S=1$ in the transverse field $\Gamma$. This allows the behaviour of the initial model to be calculated in the vicinity of its thermodynamic anomaly. In the second order, the dependence of the free
energy on temperature, and the tunneling parameter $\Gamma$ was found.
