摘要：

For a single free scalar field in d >= 2 dimensions, almost all the unitary conformal defects must be 'trivial' in the sense that they cannot hold interesting dynamics. The only possible exceptions are monodromy defects in d >= 4 and co-dimension three defects in d >= 5. As an intermediate result we show that the n-point correlation functions of a conformal theory with a generalized free spectrum must be those of the generalized free theory.
