Absorption and Emission Dependences on Defect in CLC
A. H. Gevorgyan, K. B. Oganesyan, Yu. V. Rostovtsev +2
The influence of the defect position on absorption and emission in the cholesteric liquid crystal with an isotropic defect inside is studied. It is shown that for non-diffracting c…
Threshold behavior of free electron lasers without inversion
Dmitry N. Klochkov, Ashot H Gevorgyan, Koryun B. Oganesyan +4
The interaction between noncolinear laser and relativistic electron beams in static magnetic undulator has been studied within the framework of dispersion equations. For a free-ele…
Physics of Cold Atomic Fermi Gases
E. A. Ayryan, K. G. Petrosyan, A. H. Gevorgyan +2
We consider a cold two-species atomic Fermi gas confined in a trap. We combine the Hermitian coupling between the states (we assume them to be the states with different spins) with…
Electrons for Detection of Casimir Photons
Edik A. Ayryan, Karen G. Petrosyan, Ashot H. Gevorgyan +2
We propose a method for the detection of a dynamical Casimir effect. Assuming that the Casimir photons are being generated in an electromagnetic cavity with a vibrating wall (dynam…
X-Ray Radiation Generation in Heat Engines Using Electron Cooling
E. A. Ayryan, M. Hnatic, K. G. Petrosyan +3
We consider a relativistic quantum heat engine that goes through a thermodynamical cycle consisting of stages involving laser-assisted cooling of electrons and the generation of Xr…
The critical Ising model on a torus with a defect line
Armen Poghosyan, Nikolay Izmailian, Ralph Kenna
The critical Ising model in two dimensions with a defect line is analyzed to deliver the first exact solution with twisted boundary conditions. We derive exact expressions for the…
Asymptotic expansion for the resistance between two maximum separated nodes on a resistor network
N. Sh. Izmailian, Ming-Chang Huang
We analyze the exact formulae for the resistance between two arbitrary notes in a rectangular network of resistors under free, periodic and cylindrical boundary conditions obtained…
Exact solution of a Z(4) gauge Potts model on planar lattices
N. S. Ananikian, R. G. Ghulghazaryan, N. Sh. Izmailian +1
The exact solution of a general Z(4) gauge Potts model with a single and double plaquette representation of the action is found on a subspace of gauge-coupling parameters on the sq…
An Ising spin - S model on generalized recursive lattice
N. S. Ananikian, N. Sh. Izmailian, K. A. Oganessyan
The Ising spin - S model on recursive p - polygonal structures in the external magnetic field is considered and the general form of the free energy and magnetization for arbitrary…
Chaos in the Z(2) Gauge Model on a Generalized Bethe Lattice of Plaquettes
N. S. Ananikian, S. K. Dallakian, N. Sh. Izmailian +1
We investigate the Z(2) gauge model on a generalized Bethe lattice with three plaquette representation of the action. We obtain the cascade of phase transitions according to Feigen…
