Sum rules for four-spinon dynamic structure factor in XXX model
B. Si Lakhal, A. Abada
In the context of the antiferromagnetic spin 1/2 Heisenberg quantum spin chain (XXX model), we estimate the contribution of the exact four-spinon dynamic structure factor by…
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.…
Disoriented chiral condensate formation from tubes of hot quark plasma
Abdellatif Abada, Michael C. Birse
We investigate the time evolution of a system of quarks interacting with sigma and pion fields starting from an initial configuration consisting of a tube of hot quark plasma under…
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…
Coherent amplification of classical pion fields during the cooling of droplets of quark plasma
Abdellatif Abada, Michael C. Birse
In the framework of the linear sigma model, we study the time evolution of a system of classical and pion fields coupled to quarks. For this purpose we solve numerically the cl…
Isoscalar NN spin-orbit potential from a Skyrme model with scalar mesons
Abdellatif Abada
As a first step toward circumventing the difficulty to obtain an attractive isospin-independent NN spin-orbit force from Skyrme-type models involving only pions, we investigate an…
