#### 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

(Elsevier, 2000)

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

(Taylor & Francis, 2009-05-29)

#### Simple test for hidden variables in spin-1 systems

(2008)

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

(Elsevier, 2009-12)

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

(Elsevier, 2002)

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. ...
