Geometry of Generalized Coherent States : Some Calculations of Chern Characters

نویسنده

چکیده

This is a continuation of the preceding paper (hep–ph/0108219). First of all we make a brief review of generalized coherent states based on Lie algebra su(1,1) and prove that the resolution of unity can be obtained by the curvature form of some bundle. Next for a set of generalized coherent states we define a universal bundle over the infinite–dimensional Grassmann manifold and construct the pull–back bundle making use of a projector from the parameter space to this Grassmann one. We mainly study Chern characters of these bundles. Although the Chern characters in the infinite–dimensional case are in general not easy to calculate, we can perform them for the special cases. In this paper we report our calculations and propose some problems. E-mail address : [email protected] Home-page : http://fujii.sci.yokohama-cu.ac.jp

Geometry of Coherent States : Some Examples of Calculations of Chern–Characters

First we make a brief review of coherent states and prove that the resolution of unity can be obtained by the 1–st Chern character of some bundle. Next we define a Grassmann manifold for a set of coherent states and construct the pull–back bundle making use of a projector from the parameter space to this Grassmann manifold. We study some geometric properties (Chern–characters mainly) of these b...

An Entanglement Study of Superposition of Qutrit Spin-Coherent States

Considering generalized concurrence as the criterion of entanglement, we study entanglement properties of superposition of two qutrit coherent states, as a function of their amplitudes. These states may attain maximum entanglement or no entanglement at all, depending on the choice of the parameters involved. The states revealing maximum entanglement also display the maximum violations of the Be...

Some Properties of Generalized Hypergeometric Thermal Coherent States

Abstract: The generalized hypergeometric coherent states (GHCSs) have been introduced by Appl and Schiller [1]. In the present paper we have extended some considerations about GHCSs to the mixed (thermal) states and applied, particularly, to the case of pseudoharmonic oscillator (PHO). The Husimi’s Q distribution function and the diagonal P distribution function, in the GHCSs representation, ha...

Quantum Information Theory

The purpose of this paper is to introduce several basic theorems of coherent states and generalized coherent states based on Lie algebras su(2) and su(1,1), and to give some applications of them to quantum information theory for graduate students or non–experts who are interested in both Geometry and Quantum Information Theory. In the first half we make a general review of coherent states and g...

Quasiclassical Calculations in Beam Dynamics

We present some applications of general harmonic/wavelet analysis approach (generalized coherent states, wavelet packets) to numerical/analytical calculations in (nonlinear) quasiclassical/quantum beam dynamics problems. (Naive) deformation quantization, multiresolution representations and Wigner transform are the key points.
