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…
Permanent Magnets Undulator for Terahertz FEL
M. L. Petrosyan, L. A. Gabrielyan, Yu. R. Nazaryan +5
The terahertz FEL ferromagnetic undulator has been created. The length of the undulator period is 9cm, number of the periods is 27. By means of selection and redistribution of magn…
Composite Cell from Nematic and Cholesteric Liquid Crystals as an Rotator of Electrically Tunable Polarization Plane
A. H. Gevorgyan, K. B. Oganesyan, E. A. Ayryan +6
A liquid crystal optical device made of an optically anisotropic heterostructure is considered. The device consists of a cholesteric liquid crystal (CLC) layer sandwiched by two ph…
