arXivHTMLPDF

Abstract

The structure of the state-vector space for the two-mode parabose system is investigated and a complete set of state vectors is constructed. The basis vectors are orthonormal in order p = 2. In order p = 2, conserved-charge parabose coherent states are constructed and an explicit completeness relation is obtained.

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.

Eigenstates of Paraparticle Creation Operators

Jing, S, Nelson, C A

Eigenstates of the parabose and parafermi creation operators are constructed. In the Dirac contour representation, the parabose eigenstates correspond to the dual vectors of the parabose coherent states. In order $p=2$, conserved-charge parabose creation operator eigenstates are also constructed. The contour forms of the associated resolutions of unity are obtained.

Space Structure for the Simplest Parasupersymmetric System

Wei Yang, Si Cong Jing

Structure of the state-vector space for a system consisting of one mode parabose and one mode parafermi degree of freedom with the same parastatistics order $p$ is studied and a complete, orthonormal set of basis vectors in this space is constructed. There is an intrinsic double degeneracy for state vectors with $m$ parabosons and $n$ parafermions, where $m \not= 0$, $n \not= 0$, and $n \not= p$. It is also shown that the degeneracy plays a key role in realization of exact supersymmetry for such a system.

Parabose Coherent States Based on Green's Ansatz

Minglun Gong, Ren-Shan

The coherent states of parabose oscillator of order p based on the well-known Green's ansatz have been constructed. Furthermore, it is shown that the completeness relation for these coherent states may be expressed in the form of 2×2 matrix.
