A bosonic realisation of the 1-D parabose oscillator

R. J. Cova

Published Jan 1, 2008• 0 citations
OpenAlex

Abstract

In the Fock space of two Bose operators all the representations of the 1-D Parabose oscillator are realised. States of (p+2n-1) bosons are shown to stand for states of n parabosons of order p.

A Bose description of the 1-D para-Bose and para-Fermi oscillators

R. J. Cova

In the Fock space of two Bose operators all the irreducible representations of both the 1-D para-Bose and para-Fermi oscillators are constructed. Bose states of the form |p + k–1, kn > (|p – k, kn), n = 1,2, are shown to stand for states of k-parabosons (k-parafermions) of order p. For n = 1 or n = 2 the various subspaces may be visualized in the plane as either straight-lines or parabolae, respectively.

Coherent states for parabosons

Bijan Kumar Bagchi, Debajyoti Bhaumik

Taking into consideration that the Fock space of a parabose oscillator may be described by bilinear commutation relations involving creation and annihilation operators, we construct the coherent states for odd and even order parabosons.

SQUEEZED STATES FOR PARABOSONS

Bijan Kumar Bagchi, Debajyoti Bhaumik

Squeezed states for parabosons are constructed since we know that a parabose oscillator can be parametrized in terms of bosonic operators. We also discuss some of their important properties.

Explicit representations of a single parabose operator

Doug Gray, C. A. Hurst

Representations for a single parabose operator are found as operators over a Bargmann and over a Schrödinger or harmonic oscillator space. The equivalence of the two representations is proved by the construction of a unitary integral transform connecting them.

Algebraic structure of parabose Fock space. I. The Green’s ansatz revisited

Alan Macfarlane

A description of the Fock space of a parabose oscillator of order p based on commutation relations bilinear in creation and annihilation operators rather than trilinear ones is developed. A new statement of the well-known Green’s ansatz is introduced to help understand the significance of the bilinear commutation relations. It is also applied to show how all parabose oscillators of even order (respectively, odd order) can be obtained as irreducible constituents of the Fock space associated with a Green’s ansatz of two (three) terms. Analogs of the form in which the parabose Green’s ansatz is presented are provided for one parafermi oscillator and for systems of many parabose and parafermi oscillators of the same order. Methods used in the paper allow various new results for q-deformed parabose oscillators to be derived.
