Quantum spectral curve for planar N = 4 super-yang-mills theory
KTH, Centres, Nordic Institute for Theoretical Physics NORDITA.
2014 (English)In: Physical Review Letters, ISSN 0031-9007, E-ISSN 1079-7114, Vol. 112, no 1, 011602- p.Article in journal (Refereed) Published
Abstract [en]

We present a new formalism, alternative to the old thermodynamic-Bethe- ansatz-like approach, for solution of the spectral problem of planar N=4 super Yang-Mills theory. It takes a concise form of a nonlinear matrix Riemann-Hilbert problem in terms of a few Q functions. We demonstrate the formalism for two types of observables - local operators at weak coupling and cusped Wilson lines in a near Bogomol'nyi-Prasad-Sommerfield limit.
