Polar optical scattering in ellipsoidal nanoclusters
Hrach Nikoghosyan, Gor Nikoghosyan
The influence of the specific geometry of three-dimensional confinement on electron- vibrational coupling in InAs/GaAs nanoclusters shaped as highly oblate ellipsoids of revolution…
Unipolar opical transitons in nanoclusters of ellipsoidal geometry
G. Nikoghosyan, H. S. Nikoghosyan
The quantum states of an ellipsoidal nanocluster of a heterophase system InAs / GaAs are studied using an exact analytical approach, in contrast to the generally accepted theoretic…
Electromagnetic vacuum densities induced by a cosmic string
A. A. Saharian, V. F. Manukyan, N. A. Saharyan
We investigate the influence of a generalized cosmic string in (D+1) -dimensional spacetime on the local characteristics of the electromagnetic vacuum. Two special cases are consid…
Electromagnetic vacuum fluctuations around a cosmic string in de Sitter spacetime
A. A. Saharian, V. F. Manukyan, N. A. Saharyan
The electromagnetic field correlators are evaluated around a cosmic string in background of -dimensional dS spacetime assuming that the field is prepared in the Bunch-Davies…
Electromagnetic Casimir densities for a cylindrical shell on de Sitter space
A. A. Saharian, V. F. Manukyan, N. A. Saharyan
Complete set of cylindrical modes is constructed for the electromagnetic field inside and outside a cylindrical shell in the background of % -dimensional dS spacetime. On th…
