Integrable lattice models from four-dimensional field theories [PDF]
Kevin J. CostelloThis note gives a general construction of an integrable lattice model (and a solution of the Yang-Baxter equation with spectral parameter) from a four-dimensional field theory which is a mixture of topological and holomorphic. Spin-chain models arise in this way from a twisted, deformed version of N=1 gauge theory.View original: http://arxiv.org/abs/1308.0370
