M. Arik et al., BRAID GROUP-RELATED ALGEBRAS, THEIR REPRESENTATIONS AND GENERALIZED HYDROGENLIKE SPECTRA, Journal of mathematical physics, 35(6), 1994, pp. 3074-3088
Representations of the n-braid group where generators are given by mat
rices whose elements belong to a noncommutative algebra are discussed.
Representation of this algebra in a Hilbert space generalizes the Bur
au representation. Two algebras which are closely related and are phys
ically indistinguishable provided that a particular eigenvalue is fine
tuned are discussed. It is shown that the generalized oscillator syst
em given by one of the algebras generates a hydrogenlike spectrum.
