In this work we performed a photometric and spectral study of the polar V379 Vir. We used the modeling of the IR light curves based on a simple model of cyclotrone radiation source, the method of synthetic photometry to fit the observed spectral distribution of the energy, as well as the modeling of the magnetic curve obtained from Zeeman splitting of the Hβ line to determine the parameters of the system. We managed to estimate the temperature of the white dwarf Teff = 11 450 K, the masses and radii of the primary and secondary components: M1 = 0.696 M , R1 = 0.011 R , M2 = 0.105 M , R2 = 0.14 R . The separation of the components was about 0.6 AU, and the inclination i lies in the range 47—60◦.

Quantizing Magnetic Field

We have investigated the α–T3 model in the presence of a mass term which opens a gap in the energy dispersive spectrum, as well as under a uniform perpendicular quantizing magnetic field. The gap opening mass term plays the role of Zeeman splitting at low magnetic fields for this pseudospin-1 system, and, as a consequence, we are able to compare physical properties of the the α–T3 model at low and high magnetic fields. Specifically, we explore the magnetoplasmon dispersion relation in these two extreme limits. Central to the calculation of these collective modes is the dielectric function which is determined by the polarizability of the system. This latter function is generated by transition energies between subband states, as well as the overlap of their wave functions.

Luttinger Hamiltonian

Within the Luttinger Hamiltonian, electric-field-induced resonant spin polarization of a two-dimensional hole gas in a perpendicular magnetic field was studied. The spin polarization arising from splitting between the light and the heavy hole bands shows a resonant peak at a certain magnetic field. Especially, the competition between the Luttinger term and the structural inversion asymmetry leads to a rich resonant peaks structure, and the required magnetic field for the resonance may be effectively reduced by enlarging the effective width of the quantum well. Furthermore, the Zeeman splitting tends to move the resonant spin polarization to a relative high magnetic field and destroy these rich resonant spin phenomena. Finally, both the height and the weight of the resonant peak increase as the temperature decreases. It is believed that such resonant spin phenomena may be verified in the sample of a two-dimensional hole gas, and it may provide an efficient way to control spin polarization by an external electric field.
