Peculiarities of the dynamics of a nonlinear oscillator in a constant-temperature chamber and the possible inadequacy of the phonon picture in β-zirconium
The stochastic equations of motion of a particle in a bistable potential have been studied numerically for the case in which the temperature is comparable with the height of the potential barrier. Analysis of the results of this study makes it possible to give a qualitative explanation of a number of unusual features of the lattice dynamics of Ti and Zr and their alloys.
