نویسنده
چکیده
Various forms of the q-boson are explained and their hidden symmetry revealed by transformations using the exponential phase operator. Both the one-component and the multicomponent q-bosons are discussed. As a byproduct, we obtain a new boson algebra having a shifted vacuum structure and define a global operatal U(1) gauge transformation. ∗Permanent address: Department of Physics, Jeonju University, 1200 Hyoja-3 Chonju, Chonbuk, 560-759, Korea

Using precision electroweak data, we put limits on " natural " top-color assisted technicolor models. Generically the new U (1) gauge bosons in these models must have masses larger than roughly 2 TeV, although in certain (seemingly unrealistic) models the bound can be much lower.

There are two motivations to consider statistics that are neither Bose nor Fermi: (1) to extend the framework of quantum theory and of quantum field theory, and (2) to provide a quantitative measure of possible violations of statistics. After reviewing tests of statistics for various particles, and types of statistics that are neither Bose nor Fermi, I discuss quons, particles characterized by ...

We show that on the dual of a Lie algebra g of dimension d, the star-product recently introduced by M. Kontsevich is equivalent to the Gutt star-product on g *. We give an explicit expression for the operator realizing the equivalence between these star-products.

This paper aims to study the q-wavelet and the q-wavelet transforms, associated with the q-Bessel operator for a fixed q ∈]0, 1[. As an application, an inversion formulas of the q-Riemann-Liouville and q-Weyl transforms using qwavelets are given. For this purpose, we shall attempt to extend the classical theory by giving their q-analogues.

For the critical XXZ model, we consider the space W [α] of operators which are products of local operators with a disorder operator. We introduce two anti-commutative family of operators b(ζ), c(ζ) which act on W [α]. These operators are constructed as traces over representations of the q-oscillator algebra, in close analogy with Baxter's Q-operators. We show that the vacuum expectation values ...
