We derive an expression for the linewidth of phonons involved in the order phase transitions in solids. The linewidth is obtained as a function of the dwell time from which the activation energy can be computed. A new viewpoint is presented on the assumption that the fluctuations in the random variable of the noise, which is carried by the random particles involved in the order disorder mechanism, affect the linewidth of the phonons.

THERMODYNAMIC QUANTITIES AT HIGH PRESSURES IN THE i AND theta PHASES OF SOLID NITROGEN DEDUCED BY RAMAN FREQUENCY SHIFTS FOR THE INTERNAL MODES IN LITERATURE Yurtseven, Hasan Hamit (World Scientific Pub Co Pte Lt, 2013-04-10) The pressure dependence of the Raman frequencies of the internal modes is analyzed (T = 300 K) for the phases i and theta of solid nitrogen using the experimental data from the literature. Through the mode Gruneisen parameter, the isothermal compressibility kappa(T), thermal expansion alpha(p) and the specific heat C-p - C-v are calculated as a function of pressure using the Raman data in these phases.
JOINT ENTROPY OF THE HARMONIC OSCILLATOR WITH TIME-DEPENDENT MASS AND/OR FREQUENCY Akturk, Ethem; ÖZCAN, ÖZGÜR; Sever, Ramazan (World Scientific Pub Co Pte Lt, 2009-04-30) Time-dependent joint entropy is obtained for harmonic oscillator with the time-dependent mass and frequency case. It is calculated by using time-dependent wave function obtained via Feynman path integral method. Variation of time dependence is investigated for various cases.
RAMAN STUDY OF BENZENE NEAR THE MELTING POINT Yurtseven, Hasan Hamit (World Scientific Pub Co Pte Lt, 2013-06-10) We calculate here the Raman frequencies of some lattice modes as a function of pressure at constant temperatures for the solid and liquid phases of benzene. The observed data for the molar volume from literature is used to calculate the Raman frequencies through the mode Gruneisen parameter in benzene.
RAMAN FREQUENCIES CALCULATED FROM THE VOLUME DATA AS A FUNCTION OF TEMPERATURE AT HIGH PRESSURES FOR THE DISORDERED PHASE II OF NH4I Yurtseven, Hasan Hamit (World Scientific Pub Co Pte Lt, 2011-02-10) In this study, we calculate the Raman frequencies as a function of temperature for the fixed pressures of 706, 1080 and 6355 bars using the volume data for phase 11 of ammonium iodide. The Raman frequencies calculated here are for the translational optic nu(5) TOM (125 cm(-1)) lattice mode that is located at the zone boundary (M point) of the Brillouin zone of phase II for NH4I. For this calculation the volume data obtained at zero pressure, is used through the mode Gruneisen parameter for the disordered ph...
TILT ANGLE AND THE TEMPERATURE SHIFTS CALCULATED AS A FUNCTION OF CONCENTRATION FOR THE AC* PHASE TRANSITION IN A BINARY MIXTURE OF LIQUID CRYSTALS Yurtseven, Hasan Hamit (World Scientific Pub Co Pte Lt, 2011-05-20) We study here the tilt angle and the temperature shifts as a function of concentration for the AC* phase transition in a binary mixture, using our mean field model with the biquadratic P-2 theta(2) coupling - and also with the bilinear P theta and P-2 theta(2) couplings. By expanding the free energy in terms of the tilt angle and polarization, the tilt angle and the temperature shift, are evaluated by using the coefficients given in the free energy expansion. By employing a concentration-dependent coefficie...
