Revisiting the Exact Dynamical Structure Factor of the Heisenberg Antiferromagnetic Model
A. H. Bougourzi
We revisit our initial derivations of the exact 2-spinon and 4-spinon dynamical structure factors (DSF). First we show that the latter derivations had normalization fac…
Exact four-spinon dynamical correlation function in isotropic Heisenberg model
A. Abada, A. H. Bougourzi, S. Seba +1
We discuss some properties of the exact four-spinon dynamical correlation function in the antiferromagnetic spin 1/2 -model, the expression of which we derived recently.…
Exact two-spin dynamic structure factor of the one-dimensional s=1/2 Heisenberg-Ising antiferromagnet
A. Hamid Bougourzi, Michael Karbach, Gerhard Müller
The exact 2-spinon part of the dynamic spin structure factor for the one-dimensional =1/2 model at =0 in the antiferromagnetically ordered phase is calcul…
Bosonization of quantum affine groups and its application to the higher spin Heisenberg model
A. H. Bougourzi
In this paper, we present a detailed analysis of the diagonalization of the higher spin Heisenberg model using its quantum affine symmetry . In particular, we des…
Exact four-spinon dynamical correlation function of the Heisenberg model
A. Abada, A. H. Bougourzi, B. Si-Lakhal
In this paper we derive the exact expression of the four-spinon contribution to the dynamical correlation function of the spin S= 1/2 anisotropic (XXZ) Heisenberg model in the anti…
A Hopf algebra isomorphism between two realizations of the quantum affine algebra
A. H. Bougourzi, A. Sebbar
We consider the algebra isomorphism found by Frenkel and Ding between the RLL and the Drinfeld realizations of . After we note that this is not a Hopf algebra…
