چکیده
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.

We have constructed the coherent state of U(N, 1) , which is an extension of the Barut-Girardello (BG) coherent state of SU(1, 1), in our previous paper. However there is a restriction that the eigenvalue of the Casimir operator is natural number. In this paper we construct the coherent state in the analytic representation to overcome this restriction. Next we show that the measure of the BG co...
متن کامل6 J an 2 00 3 Entanglement via Barut - Girardello coherent state for su q ( 1 , 1 ) quantum algebra : bipartite composite system
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: ra...
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 کاملBarut-Girardello coherent states for sp(N,C) and multimode Schrödinger cat states
Overcomplete families of states of the type of Barut-Girardello coherent states (BG CS) are constructed for noncompact algebras u(p, q) and sp(N,C) in quadratic bosonic representation. The sp(N,C) BG CS are obtained in the form of multimode ordinary Schrödinger cat states. A set of such macroscopic superpositions is pointed out which is overcomplete in the whole N mode Hilbert space (while the ...
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...
