This study gives a generalised smectic-hexatic phase diagram calculated by the Landau mean field theory. Our calculated phase line equations are fitted to the experimental phase lines, which represent first-order transition for the liquid crystals studied here. The temperature-and concentration-dependent phase lines calculated in this study describe the observed T-X phase diagram for the smectic-hexatic transitions. This indicates that the method of calculating the phase line equations from the mean field theory is general and it can be applied to other phase transitions in liquid crystals.

Calculation of the phase diagram using the Landau-mean-field theory for K2S2O7-KHSO4 Sen, S.; Yurtseven, Hasan Hamit (Elsevier BV, 2009-03-15) In this study a T-X phase diagram of K2S2O7-KHSO4 is calculated using the Landau-mean-field theory. By expanding the free energies of the solid phases of I, II and III in terms of the order parameters, the phase line equations are obtained among the following transitions: liquid-solid I, liquid-solid II, solid I-solid II, solid II solid III and liquid-solid III in K2S2O7-KHSO4.
Calculation of a phase diagram for the ice II-V-VItransitions Tari, O; Yurtseven, Hasan Hamit; Salihoglu, S (2000-12-01) In this study we calculate the P - T phase diagram of ice II - V - VI using a mean field model. Our calculated phase line equations are fitted to the experimental data from the literature. There is a very good agreement between our calculated and experimentally observed P - T phase diagram of ice II - V - VI.
Calculation of the Raman frequencies as a function of temperature in phase I of benzene Tari, O.; Yurtseven, Hasan Hamit (2013-06-01) This study gives our calculation of the Raman frequencies of the lattice modes A (A(1g)), B (A(g)B(2g)) and C (B1gB3g) as a function of temperature at constant pressures of 0, 1.4 and 3.05 GPa for the solid phase I of benzene. The Raman frequencies of those lattice modes are calculated using the volume data from the literature through the mode Gruneisen parameters for the solid phase I of this molecular crystal. It is shown here that the Raman frequencies of the lattice modes studied decrease with increasin...
Calculation of the H-T phase diagram, magnetization and susceptibility in layered structures Yurtseven, Hasan Hamit; Emre, B.; Acet, M. (2015-11-01) The magnetic Field-temperature (H-T) phase diagram is calculated using the mean held theory by expanding the free energy in terms of the uniform and staggered magnetization for the ferromagnetic-antiferromagnetic transitions in the La0.6Nd0.4Mn2Si2 multilayer structures. Using our experimental measurements, analysis of the magnetization as a function of the magnetic held at constant temperatures from 45 K to 250 K is performed by a power-law formula close to the ferromagnetic-antiferromagnetic transitions. ...
Analysis of various polarization asymmetries in the inclusive b -> s a"" (+) a"" (-) decay in the fourth-generation standard model BASHIRY, VALİ; Bayar, M. (Springer Science and Business Media LLC, 2009-06-01) In this study a systematical analysis of various polarization asymmetries in inclusive b -> s a"" (+) a"" (-) decay in the standard model (SM) with four generation of quarks is carried out. We found that the various asymmetries are sensitive to the new mixing and quark masses for both of the mu and tau channels. Sizable deviations from the SM values are obtained. Hence, b -> s a"" (+) a"" (-) decay is a valuable tool for searching physics beyond the SM, especially in the indirect searches for the fourth-gen...
