Form factors of integrable Heisenberg (higher) spin chains

Castro-Alvaredo, O. and Maillet, J. M. (2007). Form factors of integrable Heisenberg (higher) spin chains. Journal of Physics A: Mathematical and General, 40(27), pp. 7451-7471. doi: 10.1088/1751-8113/40/27/004

Abstract

We present determinant formulae for the form factors of spin operators of general integrable XXX Heisenberg spin chains for arbitrary (finite-dimensional) spin representations. The results apply to any 'mixed' spin chains, such as alternating spin chains, or to spin chains with magnetic impurities.
