N=2 Superconformal boundary states for free bosons and fermions
Matthias R. Gaberdiel, Hanno Klemm
TL;DR
This paper constructs the most general N=2 superconformal boundary states for a free boson-fermion system and finds they are limited to Dirichlet and Neumann states with electric fields.
Contribution
It explicitly classifies all N=2 superconformal boundary states for the c=3 free boson-fermion theory, revealing they are only Dirichlet or Neumann types.
Findings
Boundary states are only Dirichlet or Neumann with electric fields.
Constructed the most general N=2 superconformal boundary states.
Clarified the structure of boundary states in this theory.
Abstract
The most general N=2 superconformal boundary states for the c=3 theory consisting of two (uncompactified) free bosons and fermions are constructed. It is shown that the only N=2 boundary states are the familiar Dirichlet boundary states, as well as the Neumann boundary states with an arbitrary electric field.
