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 phase diagram of n-alkanes (CnH2n+2) by the Landau mean field theory Yurtseven, Hasan Hamit; Kilit Dogan, E. (2022-05-01) We study the temperature T and concentration n (number of carbon atoms) dependence on the transitions of the liquid, rotator (RI, RII,RIII,RIVand RV) and crystal phases in n-alkanes (CnH2n+2). The Landau phenomenological model is used by expanding the free energy in terms of the lattice distortion parameter (D) and the tilt angle (θ) of the rotator (and crystal) phases with their quadratic coupling (D2θ2).The phase line equations are obtained with some approximations by considering the first order transitio...
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.
Calculation of the specific heat for ND4Br close to phase transitions Yurtseven, Hasan Hamit (2002-03-01) This study gives our calculation for the specific heat close to the phase transitions from the disordered (phase 11) to the antiferro-ordered (phase 111) and to the ferro-ordered (phase IV) phases in ND4Br. We calculate the specific heat C-VI due to the nearest-neighbour interactions between ND4+. tetrahedra in the ND4Br crystal, by using an Ising model superimposed on an Einstein and/or Debye model which we have developed. Our calculated specific heat C-VI agrees well with the experimental C-p data for the...
Calculation of the Raman and IR frequencies from the volume data at high pressures in N-2 AKAY, ÖZGE; Yurtseven, Hasan Hamit (2018-01-01) Raman and IR frequencies of N-2 in the molecular state are calculated as a function of pressure up to 160 GPa by using the volume data from the literature through the mode Gruneisen parameter. By determining the Gruneisen parameters for the lattice modes and vibrons which decrease mostly with increasing pressure from the observed frequency (Raman, IR) and volume data, the Raman and IR frequencies of those modes are calculated at various pressure at room and low temperatures. We find that the Raman and IR fr...
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. ...
