Abstract
Boundary flow in the c = 1 2d CFT of a Z 2orbifold of a free boson on a circle is considered. Adding a bulk marginal operator to the c = 1 orbifold branch induces a boundary flow. We show that this flow is consistent for any bulk marginal operator and known initial given boundary condition. The supersymmetric c=3/2 case is also mentioned. For the circle branch of the moduli space, this has been shown by Fredenhagen et al (2007 J. Phys. A: Math. Theor. 40 F17). The ground state multiplicity (g b) is calculated and it is shown that it does indeed decrease.
