Abstract
Low lying states of a 2D electron-hole system contain electrons and one or more types of charged excitonic complexes. Binding energies and angular momenta of these excitonic ions, and the pseudopotentials describing their interactions with electrons and with one another are obtained from numerical studies of small systems. Incompressible fluid ground states of such multi-component plasmas are found in exact numerical diagonalizations. A generalized composite Fermion (CF) picture involving Chern--Simons charges and fluxes of different types is proposed and shown to predict the low lying states at any value of the magnetic field.
