Abstract

A long wavelength, low-energy excitation of the fractional quantum Hall state at =1/3 has been observed by inelastic light scattering. The mode appears as a very sharp peak with marked temperature and magnetic field dependence. Its energy is consistent with theoretical predictions for the collective gap excitations of the incompressible quantum fluid. Spectra interpreted as q=0 collective spin-wave excitations also display the strong dependence on field and temperature associated with the fractional quantum Hall state.
