Spectroscopy of Quantum Hall Edge States at Complex Filling Factors

摘要: We propose direct experimental tests of the effective models fractional quantum Hall edge states. first illustrate classification with example a fluid at filling factor 2/3. show that, in this example, it is impossible to describe states only one chiral channel and that there are several inequivalent two fields. focus our attention on four simplest 2/3 evaluate charges scaling dimensions quasi-particles. study transport through an electronic Fabry-Perot interferometer properties Fourier components Aharonov-Bohm oscillations current provide information about electric Thus, such interferometers can be used discriminate between different fluids corresponding same factor.
