© 2022 Elsevier B.V.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

This study gives the calculation of the Raman bandwidths using the models of the pseudospin-phonon coupling (PS) and energy fluctuation (EF) where the Raman frequency calculated from the molecular field theory, is considered as the order parameter cl

Temperature dependences of the Raman frequency shifts and linewidths of vibrons ν1, ν2 and ν22 are calculated from the anharmonic self energy in the ε, δloc (localized δ) and δ phases of solid nitrogen (P = 18.5 GPa). This is performed by fitt

Thermodynamic quantities are calculated as a function of temperature by using Landau mean-field model for the alpha-beta transition in quartz. By expanding the Gibbs free energy in terms of the order parameter (Q) with the cubic term (Q(3)), the temp

We study the two-sublattice model in the mean field theory by expanding the Gibbs free energy in terms of the magnetizations M1 (Mup) and M2 (Mdown) with the quadratic coupling M12M22 (quadrupolar interactions) for the order–disorder transition in

Raman frequencies of six lattice modes are calculated as a function of pressure using the volume data from the literature by means of the isothermal mode Gruneisen parameter (gamma(T)) for the solid phase I of benzene. We find that by determining the
