Fermionic condensate and the Casimir effect in cosmic string spacetime
A. Kh. Grigoryan, A. R. Mkrtchyan, A. A. Saharian
We investigate combined effects of nontrivial topology, induced by a cosmic string, and boundaries on the fermionic condensate and the vacuum expectation value (VEV) of the energy-…
Coherent bremsstrahlung in periodically deformed crystals with a complex base
A. R. Mkrtchyan, A. A. Saharian, V. V. Parazian
In the present paper we investigate coherent bremsstrahlung of high energy electrons moving in a periodically deformed single crystal with a complex base. The formula for correspon…
Photoproduction of electron-positron pairs in the presence of hyperacoustic oscillations
A. R. Mkrtchyan, L. Sh. Grigoryan, A. A. Saharian +1
We report on the recent progress in the investigation of the influence of hyperacoustic vibrations on the coherent electron-positron pair creation by high-energy photons in crystal…
Coherent pair production in deformed crystals with a complex base
A. R. Mkrtchyan, A. A. Saharian, V. V. Parazian
We investigate the coherent electron-positron pair creation by high-energy photons in a periodically deformed single crystal with a complex base. The formula for the corresponding…
On the influence of acoustic waves on coherent bremsstrahlung in crystals
A. A. Saharian, A. R. Mkrtchyan, V. V. Parazian +1
We investigate the coherent bremsstrahlung by relativistic electrons in a single crystal excited by hypersonic vibrations. The formula for the corresponding differential cross-sect…
On the theory of coherent pair production in crystals in presence of acoustic waves
A. R. Mkrtchyan, A. A. Saharian, L. Sh. Grigoryan +1
The influence of hypersonic waves excited in a single crystal is investigated on the process of electron-positron pair creation by high-energy photons. The coherent part of the cor…
