Large distance asymptotic behavior of the emptiness formation probability of the XXZ spin-1/2 Heisenberg chain
N. Kitanine, J. M. Maillet, N. A. Slavnov +1
Using its multiple integral representation, we compute the large distance asymptotic behavior of the emptiness formation probability of the XXZ spin-1/2 Heisenberg chain in the mas…
Correlation functions of the XXZ spin-1/2 Heisenberg chain at the free fermion point from their multiple integral representations
N. Kitanine, J. M. Maillet, N. A. Slavnov +1
Using multiple integral representations, we derive exact expressions for the correlation functions of the spin-1/2 Heisenberg chain at the free fermion point.
Emptiness formation probability of the XXZ spin-1/2 Heisenberg chain at Delta=1/2
N. Kitanine, J. M. Maillet, N. A. Slavnov +1
Using a multiple integral representation for the correlation functions, we compute the emptiness formation probability of the XXZ spin-1/2 Heisenberg chain at anisotropy Delta=1/2.…
Spin-spin correlation functions of the XXZ-1/2 Heisenberg chain in a magnetic field
N. Kitanine, J. M. Maillet, N. A. Slavnov +1
Using algebraic Bethe ansatz and the solution of the quantum inverse scattering problem, we compute compact representations of the spin-spin correlation functions of the XXZ-1/2 He…
