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. ...
Calculation of a generalised smectic–hexatic phase diagram in liquid crystals Yurtseven, Hasan Hamit (Informa UK Limited, 2012-5) 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 t...
Calculation of the P-T phase diagram of nitrogen using a mean field model Enginer, Y.; Algul, G.; Yurtseven, Hasan Hamit (2017-12-20) The P-T phase diagram is calculated at low and moderate pressures by obtaining the phase line equations for the transitions considered in nitrogen using the Landau phenomenological model. For some transitions, a quadratic coupling between the order parameters is taken into account in the expansion of free energies in terms of the order parameters. A quadratic function in T and P is fitted to the experimental P-T data from the literature and the fitted parameters are determined.
Calculation of the Raman frequency as a function of pressure for the phases of I, III, IV and V in cyclohexane Yurtseven, Hasan Hamit (2014-06-05) The Raman frequencies of the v(5) mode are calculated as a function of pressure up to 10 GPa (room temperature) for the phases I, III, IV and V of cyclohexane using the volume data from the literature by means of the isothermal mode Griineisen parameter gamma(T) of this mode.
