"Defect flows in conformal minimal models"

Abstract
By a defect we mean a line of inhomogeneity where the expectation values 
of fields are allowed to be discontinuous or even singular. Defects can 
also form an interface between two different theories. In the case of 
conformal field theories those defects are especially interesting which 
are invariant under scale transformations. These conformal defects are 
the fixed points of the renormalisation group flows. In the talk I will 
report a study of a simple example of a two-parameter space of 
renormalisation group flows with the aim of identifying new conformal 
defects in unitary minimal models.
