Spin chains and Gustafson’s integrals

S É Derkachov, A N Manashov

Published May 22, 2017• 7 citations
arXivHTMLPDF

Abstract

Abstract Gustafson’s integrals are multidimensional generalizations of the classical Mellin–Barnes integrals. We show that some of these integrals arise from relations between matrix elements in Sklyanin’s representation of separated variables in spin chain models. We also present several new integrals.

This work develops a new method, based on the use of Gustafson's integrals and on the evaluation of singular integrals, allowing one to establish the unitarity of the separation of variables transform for infinite-dimensional representations of rank one quantum integrable models. We examine in detail the case of the SL(2,R) spin chains.

New Separation of Variables for the Classical XXX and XXZ Heisenberg Spin Chains

Universit&, Guido Magnano, #224 +2 more

We propose a non-standard separation of variables for the classical integrable XXX and XXZ spin chains with degenerate twist matrix.We show that for the case of such twist matrices one can interchange the role of classical separating functions A(u) and B(u) and construct a new full set of separated variables, satisfying simpler equation of separation and simpler Abel equations in comparison with the standard separated variables of Sklyanin.We show that for certain cases of the twist matrices the constructed separated variables can be directly identified with action-angle coordinates.

We consider two-site XXX Heisenberg magnets with different boundary conditions, which are integrable systems on so (4) possessing additional cubic and quartic integrals of motion. The separated variables for these models are constructed using the Sklyanin method.

Form-factors and complete basis of observables via separation of variables for higher rank spin chains

Nikolay Gromov, Nicolò Primi, Paul Ryan

Abstract Integrable $$ \mathfrak{sl} $$ sl (N) spin chains, which we consider in this paper, are not only the prototypical example of quantum integrable systems but also systems with a wide range of applications. For these models we use the Functional Separation of Variables (FSoV) technique with a new tool called Character Projection to compute all matrix elements of a complete set of operators, which we call principal operators, in the basis diagonalising the tower of conserved charges as determinants in Q-functions. Building up on these results we then derive similar determinant forms for the form-factors of combinations of multiple principal operators between arbitrary factorizable states, which include, in particular, off-shell Bethe vectors and Bethe vectors with arbitrary twists. We prove that the set of principal operators generates the complete spin chain Yangian. Furthermore, we derive the representation of these operators in the SoV bases allowing one to compute correlation functions with an arbitrary number of principal operators. Finally, we show that the available combinations of multiple insertions includes Sklyanin’s SoV B operator. As a result, we are able to derive the B operator for $$ \mathfrak{sl} $$ sl (N) spin chains using a minimal set of ingredients, namely the FSoV method and the structure of the SoV basis.
