Abstract

Excitons in one-dimensional narrow-gap semiconductors of anticrossing quantum Hall edge states are investigated using a bosonization method. The excitonic states are studied by mapping the problem into a nonintegrable sine Gordon type model. We also find that many-body interactions lead to a strong enhancement of the band gap. We have estimated when an exciton instability may occur.
