Description
Electron-hole systems on a Haldane sphere are studied by exact numerical diagonalization. Low-lying states contain one or more types of bound charged excitonic complexes Xk-, interacting through appropriate pseudopotentials. Incompressible ground states of such multicomponent plasmas are found. A generalized multicomponent Laughlin wave function and composite fermion picture are shown to predict the low-lying states of an electron-hole gas at any value of the magnetic field. copyright 1999 The American Physical Society
