# XXZ SCALAR PRODUCTS, MIWA VARIABLES AND DISCRETE KP

@article{Foda2010XXZSP, title={XXZ SCALAR PRODUCTS, MIWA VARIABLES AND DISCRETE KP}, author={Omar Foda and Gus Schrader}, journal={arXiv: Mathematical Physics}, year={2010}, pages={61-80} }

We revisit the quantum/classical integrable model correspondence in the context of inhomogeneous finite length XXZ spin-1/2 chains with periodic boundary conditions and show that the Bethe scalar product of an arbitrary state and a Bethe eigenstate is a discrete KP tau-function. The continuous Miwa variables of discrete KP are the rapidities of the arbitrary state.
