Entanglement and the SU(2) phase states in atomic systems
(American Physical Society, 2002)
For the system of two identical two-level atoms interacting with a single photon, it is shown that the maximum entangled atomic states are represented by the SU(2) phase states of spin 1/2. Furthermore, it is shown that ...
Real rational surfaces are quasi-simple
(Walter de Gruyter, 2002)
We show that real rational (over ℂ) surfaces are quasi-simple, i.e., that such a surface is determined up to deformation in the class of real surfaces by the topological type of its real structure.
Easily monitored entagled state
(American Institute of Physics, 2002-12-23)
We discuss the generation and monitoring of durable atomic entangled state via Raman-type process, which can be used in the quantum information processing. (C) 2002 American Institute Of Physics.
Steady-state entanglement of two atoms created by classical driving field
(American Physical Society, 2005)
The stabilization of entanglement caused by action of a classical driving field in the system of two-level atoms with the dipole interaction accompanied by spontaneous emission is discussed. An exact solution shows that ...
On the Titchmarsh convolution theorem
Let M be the set of all finite complex-valued Borel measures μ≢0 on ℝ. Set ℓ(μ) inf(supp μ). The classical Titchmarsh convolution theorem claims that if: (i) μj ∈ M, (ii) ℓ(μj) > - ∞, j = 1,. . . , n, then ℓ(μ1) + ⋯ + ...
Parametric representation of a clas of multiply positive sequences

Simple test for hidden variables in spin-1 systems
We resolve an old problem about the existence of hidden parameters in a three-dimensional quantum system by constructing an appropriate Bell's type inequality. This reveals the nonclassical nature of most spin-1 states. ...
On the classification of Darboux integrable chains
(American Institute of Physics, 2008)
We study differential-difference equation (d/dx) t (n+1,x) =f (t (n,x),t (n+1,x), (d/dx) t (n,x)) with unknown t (n,x) depending on continuous and discrete variables x and n. Equation of such kind is called Darboux integrable, ...
Essential cohomology for elementary abelian p-groups
For an odd prime p the cohomology ring of an elementary abelian p-group is polynomial tensor exterior. We show that the ideal of essential classes is the Steenrod closure of the class generating the top exterior power. As ...
Asymptotic zero distribution of sections and tails of Mittag-Leffler functions
We study the asymptotic (as n→∞) zero distribution of where μ ∈ C, sn is nth section, tn is nth tail of the power series of classical Lindelöf function Γλ of order λ. Our results generalize the results by A. Edrei, E. B. ...
