Spin and charge density excitations and the collapse of the fractional quantum Hall state at nu=1/3
Inelastic light scattering from 2D electrons below 100 mK reveals collective charge and spin density excitations of the incompressible electron liquid at Landau level filling factor v -1/3 and provides experimental evidence for a magnetoroton minimum in the charge density dispersion curve. The tempe...
