Superconformal defects in the tricritical Ising model
Abstract
We study superconformal defect lines in the tricritical Ising model in 2 dimensions. By the folding trick, a superconformal defect is mapped to a superconformal boundary of the Script N = 1 superconformal unitary minimal model of c = 7/5 with D_{6}E_{6} modular invariant. It turns out that the complete set of the boundary states of c = 7/5 D_{6}E_{6} model cannot be interpreted as the consistent set of superconformal defects in the tricritical Ising model since it does not contain the ``no defect'' boundary state. Instead, we find a set of 18 consistent superconformal defects including ``no defect'' and satisfying the Cardy condition. This set also includes some defects which are not purely transmissive or purely reflective.
