The Algebraic Curve of 1-loop Planar N=4 SYM

Schafer-Nameki, Sakura

Original · EN

The algebraic curve for the psu (2,2|4) quantum spin chain is determined from the thermodynamic limit of the algebraic Bethe ansatz. The Hamiltonian of this spin chain has been identified with the planar 1-loop dilatation operator of N=4 SYM. In the dual AdS₅ x S⁵ string theory, various properties of the data defining the curve for the gauge theory are compared to the ones obtained from semiclassical spinning-string configurations, in particular for the case of strings on AdS₅ x S¹ and the su(2,2) spin chain agreement of the curves is shown.
