Query: Chiral Fermion and Boundary State Formulation: Resonant Point-Contact
  Tunneling   We study a model of resonant point-contact tunneling of a single
Luttinger-liquid lead, using the boundary state formulation. The model is
described by a single chiral Fermion in one dimensional space with one point
contact interaction at the origin. It is the simplest model of this type. By
folding the infinite line we map the model onto a non-chiral model on the half
infinite line and transcribe the point-contact tunneling interaction into a
boundary interaction. The tunneling interaction yields a non-local effective
action at the boundary. We explicitly construct the boundary state and evaluate
the current correlation functions. The contact interaction is shown to act on
the lower frequency modes more strongly.
