Reflection algebra, Yangian symmetry and bound-states in AdS/CFT
arXiv:1101.6062 · doi:10.1007/JHEP01(2012)134
Abstract
We present the `Heisenberg picture' of the reflection algebra by explicitly constructing the boundary Yangian symmetry of an AdS/CFT superstring which ends on a boundary with non-trivial degrees of freedom and which preserves the full bulk Lie symmetry algebra. We also consider the spectrum of bulk and boundary states and some automorphisms of the underlying algebras.
