Landau mean-field model with the cubic term for the alpha-beta transition in quartz
(2020)
Thermodynamic quantities are calculated as a function of temperature by using Landau mean-field model for the alpha-beta transition in quartz. By expanding the Gibbs free energy in terms of the order parameter (Q) with the ...
Calculation of the damping constant and the relaxation time of the LA mode in the incommensurate phase of quartz
(2021)
The damping constant (linewidth) of the LA mode is calculated as a function of temperature for the incommensurate (INC) phase of quartz by using the models of the pseudospin-phonon (PS) coupled and the energy fluctuation ...
