Symmetries in superintegrable deformations of oscillator/Coulomb systems: "holomorphic factorization"
Tigran Hakobyan, Armen Nersessian, Hovhannes Shmavonyan
We propose a unified description for the constants of motion for superintegrable deformations of the oscillator and Coulomb systems on N-dimensional Euclidean space, sphere and hyp…
Some bounds on the number of colors in interval and cyclic interval edge colorings of graphs
Carl Johan Casselgren, Hrant H. Khachatrian, Petros A. Petrosyan
An \emph{interval -coloring} of a multigraph is a proper edge coloring with colors such that the colors on the edges incident to every vertex of are colored…
Resonance fluorescence from an asymmetric quantum dot dressed by a bichromatic electromagnetic field
G. Yu. Kryuchkyan, V. Shahnazaryan, O. V. Kibis +1
We present the theory of resonance fluorescence from an asymmetric quantum dot driven by a two-component electromagnetic field with two different frequencies, polarizations and amp…
Enhanced non-resonant light transmission through subwavelength slits in metal
Anders Pors, Khachatur V. Nerkararyan, Khachik Sahakyan +1
We analytically describe light transmission through a single subwavelength slit in a thin perfect electric conductor screen for the incident polarization being perpendicular to the…
Induced fermionic charge and current densities in two-dimensional rings
S. Bellucci, A. A. Saharian, A. Kh. Grigoryan
For a massive quantum fermionic field, we investigate the vacuum expectation values (VEVs) of the charge and current densities induced by an external magnetic flux in a two-dimensi…
Further results on the deficiency of graphs
Petros A. Petrosyan, Hrant H. Khachatrian
A \emph{proper -edge-coloring} of a graph is a mapping such that all colors are used, and for every pair of adja…
