Vortex chains travelling with discrete velocities

It has been shown that Swihart waves slowing down caused by Josephson junction spatial dispersion leads to the new field periodic nonlinear vortex states moving with discrete velocities. Swihart waves trapping by periodic vortex structures is discovered.     

Ortho-para splitting of the exciton ground state in a strong magnetic field

Exciton spectra in bulk semiconductor in strong magnetic fields were studied in the two-band Dirac model. An expression for the energy of ortho-para splitting of the ground state was derived.     

Study of infrared sew reflection on a corrugated metal surface

The influence of the grating groove depth upon reflectivity (R) of SEW propagating along corrugated metal surfaces was studied. The R dependence on wavelength and angles of SEW incidence on the grating was investigated. A maximum value of reflectivity of 53% at groove depth of 0.24μm was obtained.     

Zenneck-Sommerfeld type surface polaritons on the quartz crystal

The surface polariton (SP) propagation along the quartz crystal surface in the frequency region 1050–1090 cm^-1 was studied. The propagation length of SP rises from 50 to 105 μm when the frequencies goes down to transverse frequency (where SP is actually Zenneck-Sommerfeld type mode) and drastically decreases for lower frequencies.     

Spectral-temporal investigations of the backscattered radiation from laser plasma

Spectral and time-resolved investigations of the back-scattered light from aluminium laser-produced plasmas at frequencies ω_L and 2ω_L are performed. Good correlation between maxima of the scattered light at ω_L and minima at 2ω_L was discovered. This correlation has been predicted by the theory. These experiments show that the spectrum width and intensity of the second harmonic essentially depend on the velocity of the expanding plasma.
