String integrability on the Coulomb branch
摘要
The Coulomb branch of the N = 4 super-Yang-Mills theory is described by a D3-brane in the bulk of AdS5 × S5. We show that the boundary conditions on the D-brane preserve integrability of the string sigma-model by constructing a dynamical and spectral parameter dependent reflection matrix that encodes an infinite number of conserved charges.
