Transport properties of magneto-excitations in integer and fractional quantum Hall insulators

Transport properties of magneto-excitations in integer and fractional quantum Hall insulators

Using a high-resolution optical system, we visualize and compare the real-space transport of the dense ensembles of photoexcitations in integer and fractional quantum Hall insulators at the filling factors ν = 2 and ν = 1 / 3. We analyze the correlation between the transport properties and spatial c...

Zusammenfassung:Using a high-resolution optical system, we visualize and compare the real-space transport of the dense ensembles of photoexcitations in integer and fractional quantum Hall insulators at the filling factors ν = 2 and ν = 1 / 3. We analyze the correlation between the transport properties and spatial coherence of these ensembles.
