Boundary overlap in the open XXZ spin chain
Charbel Abetian, Nikolai Kitanine, Veronique Terras
In this paper we compute the overlaps of the ground states for the open spin chains after a change of one of the boundary magnetic fields. It can be considered as the first step to…
Form Factors of the Heisenberg Spin Chain in the Thermodynamic Limit: Dealing with Complex Bethe Roots
Nikolai Kitanine, Giridhar Kulkarni
In this article we study the thermodynamic limit of the form factors of the XXX Heisenberg spin chain using the algebraic Bethe ansatz approach. Our main goal is to express the for…
Thermodynamic limit of the two-spinon form factors for the zero field XXX chain
Nikolai Kitanine, Giridhar Kulkarni
In this paper we propose a method based on the algebraic Bethe ansatz leading to explicit results for the form factors of quantum spin chains in the thermodynamic limit. Starting f…
The open XXZ spin chain in the SoV framework: scalar product of separate states
N. Kitanine, J. M. Maillet, G. Niccoli +1
In our previous paper [1] we have obtained, for the XXX spin-1/2 Heisenberg open chain, new determinant representations for the scalar products of separate states in the quantum se…
Quantum Integrability and Quantum Groups: a special issue in memory of Petr P. Kulish
Nikolai Kitanine, Rafael I. Nepomechie, Nicolai Reshetikhin
This is an introduction to Quantum Integrability and Quantum Groups, a special issue collection of articles published in Journal of Physics A in memory of Petr P. Kulish. A list of…
The open XXX spin chain in the SoV framework: scalar product of separate states
N. Kitanine, J. M. Maillet, G. Niccoli +1
We consider the XXX open spin-1/2 chain with the most general non-diagonal boundary terms, that we solve by means of the quantum separation of variables (SoV) approach. We compute…
