A note on gl_N type-I integrable defects

preprint2014arXivOpen access

Abstract

Type-I quantum defects are considered in the context of the gl_N spin chain. The type-I defects are associated to the generalized harmonic oscillator algebra, and the chosen defect matrix is the one of the vector non-linear Schrodinger (NLS) model. The transmission matrices relevant to this particular type of defects are computed via the Bethe ansatz methodology.
