6 J an 2 00 3 Entanglement via Barut - Girardello coherent state for su q ( 1 , 1 ) quantum algebra : bipartite composite system
نویسنده
چکیده
Using noncocommutative coproduct properties of the quantum algebras, we introduce and obtain, in a bipartite composite system, the Barut-Girardello coherent state for the q-deformed suq(1, 1) algebra. The quantum coproduct structure ensures this normalizable coherent state to be entangled. The entanglement disappears in the classical q → 1 limit, giving rise to a factorizable state. ∗E-mail: [email protected]

Coherent States for Kronecker Products of Non Compact Groups: Formulation and Applications
We introduce and study the properties of a class of coherent states for the group SU(1,1) X SU(1,1) and derive explicit expressions for these using the Clebsch-Gordan algebra for the SU(1,1) group. We restrict ourselves to the discrete series representations of SU(1,1). These are the generalization of the ‘Barut Girardello’ coherent states to the Kronecker Product of two non-compact groups.The ...
متن کاملBosonic and k-fermionic coherent states for a class of polynomial Weyl-Heisenberg algebras
The aim of this article is to construct à la Perelomov and à la Barut–Girardello coherent states for a polynomial Weyl-Heisenberg algebra. This generalized Weyl-Heisenberg algebra, noted A{κ}, depends on r real parameters and is an extension of the Aκ one-parameter algebra (Daoud M and Kibler M R 2010 J. Phys. A: Math. Theor. 43 115303) which covers the cases of the su(1, 1) algebra (for κ > 0)...
متن کاملExtension of the Barut-Girardello Coherent State and Path Integral
We extend the Barut-Girardello coherent state for the representation of SU(1, 1) to the coherent state for a representation of U(N, 1) and construct the measure. We also construct a path integral formula for some Hamiltonian.
متن کاملThe Abdus Salam International Centre for Theoretical Physics Entanglement Generation with Deformed Barut-girardello Coherent States as Input States in a Unitary Beam Splitter
Using linear entropy as a measure of entanglement, we investigate the entanglement generated via a beam splitter using deformed Barut-Girardello coherent states. We show that the degree of entanglement depends strongly on the q-deformation parameter and amplitude Z of the states. We compute the Mandel Q parameter to examine the quantum statistical properties of these coherent states and make a ...
متن کاملPhoton states associated with Holstein - Primakoff realization of SU ( 1 , 1 ) Lie algebra
Statistical and phase properties and number-phase uncertainty relations are systematically investigated for photon states associated with the Holstein-Primakoff realization of the SU(1,1) Lie algebra. Perelomov's SU(1,1) coherent states and the eigenstates of the SU(1,1) lowering generator (the Barut-Girardello states) are discussed. A recently developed formalism, based on the antinormal order...
