The Role of Hypersound in Stimulation of Resonant Transitions in Positronium Atom
E. A. Ayryan, A. S. Gevorkyan, M. Hnatic +2
The possibilities of stimulation of resonant transitions between quantum states of Positron Atom by the external hypersound are investigated in detail.
On a Positron Channeling in Ionic Crystals
E. A. Ayryan, A. S. Gevorkyan, M. Hnatic +4
An analytical expression is received for the effective interaction potential of a fast charged particle with the ionic crystal CsCl near the direction of axis <100> as a function o…
The Effect of Defect Layer on Lasing in Cholesteric Liquid Crystal
A. H. Gevorgyan, K. B. Oganesyan, N. Sh. Izmailian +9
The photonic density of states (PDS) of eigen polarizations (EPs) in cholesteric liquid crystal (CLC) cells with a defect layer inside are calculated. The dependences for the PDS a…
The Influence of Absorption and Gain on Photonic Density of States
A. H. Gevorgyan, K. B. Oganesyan, N. Sh. Izmailian +8
The photonic density of states (PDS) of the eigen polarizations (EPs) in cholesteric liquid crystal (CLC) cells are calculated. The exact analytic expressions for the reflection an…
Polarization Properties of the Cholesteric Liquid Crystals
A. H. Gevorgyan, M. Z. Harutyunyan, K. B. Oganesyan +5
In the present paper, we investigate the polarization properties of the cholesteric liquid crystals (CLCs) with an isotropic/anisotropic defect inside them. Possibilities of amplif…
Radiation Peculiarities in Chiral Photonic Crystals
A. H. Gevorgyan, K. B. Oganesyan, E. A. Ayryan +2
The peculiarities of defect modes and reflection spectra of chiral photonic crystals (CPC) with an isotropic defect for various thicknesses of the defect layer was investigated. Th…
