Using mean-field theory with p(2)theta(2) coupling term in the free energy expansion, we calculate the polarization as a function of concentration for the AC* phase transition in a binary mixture of C7 and 10.O.4 liquid crystalline material. Our calculated values of polarization are in good agreement with the experimental data.

TEMPERATURE DEPENDENCE OF THE RAMAN FREQUENCIES IN THE gamma AND beta PHASES OF SOLID NITROGEN
Yurtseven, Hasan Hamit (World Scientific Pub Co Pte Lt, 2010-12-20)
We study here the Raman frequencies of the lattice modes (gamma and beta phases) and of an internal mode (gamma phase) as a function of temperature in solid nitrogen. The frequency shift, derived from the anharmonic self energy, is fitted to the experimental data for the Raman frequencies of the modes considered here in the gamma and beta phases of solid nitrogen.
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...
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.
CALCULATION OF THE RAMAN FREQUENCIES AT LOW PRESSURES AND TEMPERATURES (sigma-PHASE) SOLID NITROGEN
Yurtseven, Hasan Hamit (World Scientific Pub Co Pte Lt, 2013-09-20)
We calculate the Raman frequencies of the E-g mode and, the low and high frequency T-g mode as a function of temperature at a constant pressure of 2.85 kbar in the alpha-phase of solid nitrogen. The Raman frequencies of those lattice modes are calculated using the volume data from the literature at various temperatures (2.85 kbar) for the alpha-phase of solid N-2 through the mode Gruneisen parameter. Our predicted Raman frequencies can be compared with the experimental data and by this method the Raman freq...
CALCULATION OF THE DAMPING CONSTANT AND ACTIVATION ENERGY FOR RAMAN MODES IN (NH4)(2)SO4
Yurtseven, Hasan Hamit; Kiraci, A. (World Scientific Pub Co Pte Lt, 2011-06-20)
The temperature dependence of the damping constant is calculated for various Raman modes in (NH4)(2)SO4 by the expressions derived from the soft mode hard mode coupling model and the energy fluctuation model. The expressions for the damping constant are fitted to the measured Raman bandwidths and then the activation energies are extracted, which are equal to similar to 0.2 eV for the Raman modes studied. The damping constant of a soft mode is also calculated and the activation energy (similar to 0.1 eV) is ...
