Course Syllabus
Abstract
This course is organized in the form of weekly seminars, where we are going to discuss the integrability structures appearing in quantum field theory. These structures nowadays are present in numerous examples, such as sigma models, supersymmetric gauge theories, string theories, gauge/string dualities, scattering amplitudes and correlation functions etc. In the second part of the course there will be given an introduction into the applications of the theory of integrable systems to the study of the spectrum of N=4 supersymmetric Yang-Mills theory and dual superstring theory on the AdS_5×S^5 background. The course is intended for PhD and Master students. Postdocs and Bachelor students are also welcome.
Learning Objectives
- Understand the derivation of the AdS_5 x S^5 superstring theory S-matrix with the usage of the Zamolodchikov-Faddeev algebra.
- Study the integrable structure of N=4 SYM and thus AdS_5 x S^5 superstring theory, including the 1-loop integrabiity, Thermodynamic Bethe Ansatz equations with the Y- and T-systems and the method of Quantum Spectral Curve.
- Learn about the integrable deformations of sigma models, such as O(N) sigma models and others.
Expected Learning Outcomes
- Able to solve the supergravity equations, which yield the AdS_5 x S^5 superstring background as a key element of one of the examples of AdS/CFT duality.
- Able to transform the Y-system for N=4 SYM into the T-system and solve it.
- Became aware of the notions of flatness condition, monodromy operator and quasimomenta together with the conserved charges and their analytic structure.
- Can obtain AdS_5 x S^5 superstring theory worldsheet S-matrix from Zamolodchikov-Faddeev algebra.
- Familiar with examples of calculation of the characteristics of the N=4 SYM spectrum using the Quantum Spectral Curve method.
- Knows how to derive the Quantum Spectral Curve equations for N=4 SYM and AdS_5 x S^5 superstring theory.
- Understands the 1-loop integrability of N=4 SYM, asymptotic spectrum and Thermodynamic Bethe Ansatz equations of this theory.
- Understands the transition from Y- to T-system and how to solve it.
