Dynamical Applications of Bargmann Space II. Interacting Bose-Fermi Systems

John Martin Robinson, S. L. Trubatch

Published Aug 1, 1971• 0 citations
Publisher

Abstract

Bargmann space techniques are extended to interacting Bose-Fermi systems. The one-mode Fried model is used as an illustrative example. Comparison is made with the eigenfunctions and eigenvalues obtained by direct diagonalization.

Dynamical Applications of Bargmann Space I. Pure Bose Systems

John Martin Robinson, S. L. Trubatch

Practical aspects of the Bargmann space representation of quantum mechanics are detailed. Models which are quantized by imposing the entirety and growth-rate conditions are analyzed. The extension of coherent state space techniques to multimode systems is accomplished, and some illustrative models are solved.

Dynamical Applications of Bargmann Space III. Angular Momentum

John Martin Robinson, S. L. Trubatch

The coherent state representation is developed for angular momentum operators. As an example, the one-Boson Lee model is analyzed with its Fermi operators in Bargmann space. Finally, a synthesis is achieved by analyzing the three-level system with all operators in Bargmann space.

ANALYTIC CHARACTERIZATION OF ONE-MODE INTERACTING FOCK SPACE

Nobuhiro Asai

In this paper, we shall give the Segal–Bargmann representation space of the one-mode interacting Fock space. For this purpose, we shall define the generalized coherent vector associated with the Szegö–Jacobi parameters and introduce the associated integral transformation.

Fermi-type interaction in molecular and atomic Hamiltonians. Application to molecular systems and Bose-Einstein condensates.

Claude Leroy, Artur Mikhailovich Ishkhanyan, Ruzan Sokhoyan +5 more

We present a simple prescription to build phenomenological Hamiltonians describing Fermi-type interactions and apply the developed formalism to two distinct physical systems. First, in a very simple way, we derive equations describing time dynamics of two coherently coupled Bose-Einstein condensates. Further, for bent XY2 molecules, we reproduce all the experimental data with an excellent precision.

Fock-Bargmann space and classic trajectories

GENNADY F. FILIPPOV, S. V. Korennov, A. M. Sytcheva +1 more

In recent years, a new approach to the theory of nuclear reactions leading to a break-down of the interacting subsytems into various channels has been developed. This approach was named the Antisymmetrized Molecular Dynamic (AMD), and its main idea lies in the description of the nucleons by wave packets in which the antisymmetrization effects (but not other quantum effects) are accounted for. In the present review, the basic principles of AMD are illustrated on the examples of simplest nuclear systems, and the results are compared with those provided by an exact quantum-mechanical description in the Fock-Bargmann space. The applicability region of AMD is discussed, in particular, in the cases of systems with discrete spectrum, and a relation between the classical AMD trajectories and the quantum distributions is established. At the same time, a new interpretation of Brink orbitals and Slater determinants built on them as eigenfunctions of the coordinate operator defined in the Fock-Bargmann space is proposed. It is shown that these functions form the cluster geometry of nuclear systems.
