Abstract
We construct the energy operator for particles obeying infinite statistics defined by aq-deformation of the Heisenberg algebra.
The aim of this paper is to construct the energy operator for particles which obey the so-called infinite statistics defined by theq-deformation of the Heisenberg algebra. This topic was studied in the previous article [1], where a conjecture was formulated concerning the form of the energy operator. Our main result is a proof of this conjecture in a slightly modified form (cf. Remark 1).
We will essentially use the same notations as in [1]. Thus,T 1k will denote the particular elements of\(\mathfrak{S}_n \) which send [1, 2,...,n] to [k, 1,...,k−1,k+1,...,n], ie
and
represent the following subsets of\(\mathfrak{S}_n \):
for 1≤p≤n−1 and\(\mathfrak{S}_{n,0} = \{ 1\} \). (This differs from the definition of\(\mathfrak{S}_{n,p} \) in [1].) In [1] ann!×n! matrix\(A_n (\pi ,\sigma ), \pi ,\sigma \in \mathfrak{S}_n ,\), with coefficients in ℤ[q] was studied and shown to be invertible for |q|<1. As in [1], we will work with the group algebra ℂ[G n ] rather than its matrix representation, so we have elements
Let ℰ be the energy operator of particles obeying infinite statistics, defined by the commutation relation (1) in [1]. ℰ acts on ℋ(q) and eachx 1 is an eigenvector of ℰ satisfying the eigenvalue equation
whereE(l i) is the energy of a particle with momentuml i.
