Quasistatic theory applying

The quasistatic theory does not apply in the satellite region, but some information can be derived from this region by the use of the semiclassical method of Szudy and Baylis (14). 

The purpose of this section is to show how the previous theory can be applied in practical calculations. For the time being only quasistatic processes have been... 

The purpose of this section is to show how the above theory can be applied in practical calculations. For the time being, only quasistatic processes have been studied in detail the subsequent discussion will thus focus on this limit. Two sorts of quantities enter into the theory the atom-atom distribution functions r) in a given electronic state j and the corresponding populations nj t). The total atom-atom distribution function gnv(r, t) is then... 

For such theory, a,p,y,d,2., and are expansion coefficients that are extracted from the experimentally measured quasistatic hysteretic response of a single-crystal. Physically, the first three terms of the right hand side of the first row of the Helmholtz free energy expressoin defines the equilibrium, stress and electric field free variants of the system. The fourth term couples an externally specified electric field to the local state of polarization of the solid. Such contribution biases the stability of those variants that are closer (or parallel) to the applied field. The fifth term...
