Tunneling density of states, correlation energy, and spin polarization in the fractional quantum Hall regime

Journal Article Chaudhary, Gaurav ; Efimkin, Dmitry K. ; MacDonald, Allan H. - Physical Review B

We derive exact sum rules that relate the tunneling density-of-states of spinful electrons in the fractional quantum Hall regime to the spin-dependent many-body ground-state correlation energy. Because the tunneling process is spin-conserving, the two-dimensional (2D) to 2D tunneling currentmore »« less

Edge State Propagation Direction in the Fractional Quantum Hall Regime: Multi-Terminal Magnetocapacitance Experiment

Conference JOHNSON, B L ; MOON, JEONG-SUN ; RENO, JOHN L ; ...

The propagation direction of fractional quantum Hall effect (FQHE) edge states has been investigated experimentally via the symmetry properties of the multi-terminal capacitances of a two dimensional electron gas. Although strong asymmetries with respect to zero magnetic field appear, no asymmetries with respect to even denominator Landau level filling factor {nu} are seen. This indicates that current-carrying FQHE edge states propagate in the same direction as integer QHE edge states. In addition, anomalous capacitance features, indicative of enhanced bulk conduction, are observed at {nu} = 1/2 and 3/2.

Edge-channel interferometer at the graphene quantum Hall pn junction

Journal Article Morikawa, Sei ; Moriya, Rai ; Masubuchi, Satoru ; ... - Applied Physics Letters

We demonstrate a quantum Hall edge-channel interferometer in a high-quality graphene pn junction under a high magnetic field. The co-propagating p and n quantum Hall edge channels traveling along the pn interface functions as a built-in Aharonov-Bohm-type interferometer, the interferences in which are sensitive to both the external magnetic field and the carrier concentration. The trajectories of peak and dip in the observed resistance oscillation are well reproduced by our numerical calculation that assumes magnetic flux quantization in the area enclosed by the co-propagating edge channels. Coherent nature of the co-propagating edge channels is confirmed by the checkerboard-like pattern inmore »« less

Impact of bulk-edge coupling on observation of anyonic braiding statistics in quantum Hall interferometers

Journal Article Nakamura, J. ; Liang, S. ; Gardner, G. C. ; ... - Nature Communications

Abstract Quantum Hall interferometers have been used to probe fractional charge and statistics of quasiparticles. We present measurements of a small Fabry–Perot interferometer in which the electrostatic coupling constants which affect interferometer behavior can be determined experimentally. Near the center of the ν = 1/3 state this device exhibits Aharonov–Bohm interference interrupted by a few discrete phase jumps, and Φ ₀ oscillations at higher and lower magnetic fields, consistent with theoretical predictions for detection of anyonic statistics. We estimate the electrostatic parameters K _I and K _{I L} by two methods: using the ratio of oscillation periodsmore »« less
