Excitons in an incompressible fluid: giant polaron effect
A theory is derived for 2D magnetoexcitons under the conditions of the fractional quantum Hall effect. The presence of an incompressible 2D fluid leads to a giant suppression of the exciton dispersion. The optical spectrum of the excitons is very sensitive to the geometry of the system. In the quantum limit this spectrum is trivial, being the same as the spectrum of a free exciton in the symmetric model. Under more general conditions, it becomes dependent on the filling factor.
