New Boundary Conformal Field Theories Indexed by the Simply-Laced Lie Algebras
Ali Yegulalp
We consider the field theory of massless bosons which are free except for an interaction localized on the boundary of their 1+1 dimensional world. The boundary action is the su…

Magnetic Fields and Fractional Statistics in Boundary Conformal Field Theory
C. G. Callan, I. R. Klebanov, J. M. Maldacena +1
We study conformal field theories describing two massless one-dimensional fields interacting at a single spatial point. The interactions we include are periodic functions of the bo…

Fermions Coupled to a Conformal Boundary: A Generalization of the Monopole-Fermion System
Ali Yegulalp
We study a class of models in which flavors of massless fermions on the half line are coupled by an arbitrary orthogonal matrix to rotors living on the boundary. Integratin…
