FIG. 1. b. (left) Model of the device design with dual layer gates insulated with 20 nm Al2O3 (not shown for clarity) below the fine gates and 40 nm Al2O3 below the global top gate. The first layer of fine gates defines the quantum dot, while the second layer serves as a global gate to control the carrier density.

APS Viewpoint // Fractional Jumps in Quantum Hall Interferometer

October 23, 2023

Check out American Physical Society viewpoint by Steven H. Simon, Fractional Jumps in Quantum Hall Interferometer, which focuses on the Manfra group's most recent Physical Review X publication (10.1103/PhysRevX.13.041012).

The quantum Hall interferometer consists of a two-dimensional material (blue) with a cavity structure (yellow) in its center. When a magnetic field and a voltage are turned on, currents (red lines) flow along the edge of the material. Reflections at the entrances of the cavity lead to interference effects in the measured conductance. For certain field and voltage values, the interference pattern exhibits phase jumps because of the changes in the number of quasiparticles (orange) inside the cavity. Credit: APS/A. Stonebraker

Purdue News // Purdue physicists develop experimental techniques to expose various flavors of anyons

October 23, 2023

Check out Purdue News article, Purdue physicists develop experimental techniques to expose various flavors of anyons, which focuses on the Manfra group's most recent Physical Review X publication (10.1103/PhysRevX.13.041012).


10.1103/PhysRevX.13.041012 FIG. 1. (a) False-color SEM image of an interferometer with the same dimensions as the device used in our experiment. Red lines indicate propagating edge states. The illustrated configuration corresponds to the case of ν = 2/5, where there are two edge states. (b) Conductance oscillations at ν = 1 versus magnetic field and side gate voltage VSG. The negatively sloped lines of constant phase indicate Aharonov-Bohm regime behavior, while weak modulations suggest small but finite bulk-edge coupling.
