Exactly conserved quasilocal operators for the XXZ spin chain
R. G. Pereira, V. Pasquier, J. Sirker +1
We extend T. Prosen's construction of quasilocal conserved quantities for the XXZ model [Phys. Rev. Lett. 106, 217206 (2011)] to the case of periodic boundary conditions. These qua…

Dynamical structure factor at small q for the XXZ spin-1/2 chain
R. G. Pereira, J. Sirker, J. -S. Caux +4
We combine Bethe Ansatz and field theory methods to study the longitudinal dynamical structure factor S^{zz}(q,omega) for the anisotropic spin-1/2 chain in the gapless regime. Usin…

The dynamical spin structure factor for the anisotropic spin-1/2 Heisenberg chain
R. G. Pereira, J. Sirker, J. -S. Caux +4
The longitudinal spin structure factor for the XXZ-chain at small wave-vector q is obtained using Bethe Ansatz, field theory methods and the Density Matrix Renormalization Group. I…
