Maverick Examples Of Coset Conformal Field Theories
We present coset conformal field theories whose spectrum is not determined by the identification current method. In these “maverick” cosets there is a larger symmetry identifying primary fields than under the identification current. We find an A-D-E classification of these mavericks.
متن کاملCharacters For Coset Conformal Field Theories
We present formulae for the characters of coset conformal field theories and apply these to specific examples to determine the integer shift of the conformal weights of primary fields. We also present an example of a coset conformal field theory which cannot be described by the identification current method.
متن کاملBoundary Flows in the general Coset Theories
In this paper we study the boundary effects for off-critical integrable field theories which have close analogs with integrable lattice models. Our models are the SU(2)k ⊗ SU(2)l/SU(2)k+l coset conformal field theories perturbed by integrable boundary and bulk operators. The boundary interactions are encoded into the boundary reflection matrix. Using the TBA method, we verify the flows of the c...
متن کاملBoundary states in coset conformal field theories
We construct various boundary states in the coset conformal field theory G/H. The G/H theory admits the twisted boundary condition if the G theory has an outer automorphism of the horizontal subalgebra that induces an automor-phism of the H theory. By introducing the notion of the brane identification and the brane selection rule, we show that the twisted boundary states of the G/H theory can b...
