Interference measurements of non-Abelian e/4 & Abelian e/2 quasiparticle braiding

R. L. Willett, K. Shtengel, C. Nayak +6

The quantum Hall states at filling factors and are expected to have Abelian charge quasiparticles and non-Abelian charge quasiparticles. The non-Abelian s…

Magnetic field-tuned Aharonov-Bohm oscillations and evidence for non-Abelian anyons at v=5/2

R. L. Willett, C. Nayak, K. Shtengel +2

We show that the resistance of the v=5/2 quantum Hall state, confined to an interferometer, oscillates with magnetic field consistent with an Ising-type non-Abelian state. In three…

Aharonov-Bohm effect and coherence length of charge e/4 quasiparticles at 5/2 filling factor measured in multiple small Fabry-Perot interferometers

R. L. Willett, L. N. Pfeiffer, K. W. West +1

Design of a Fabry-Perot (double point contact) interferometer to measure fractional quantum Hall effect quasiparticle charge properties, and in particular the 5/2 excitations, pose…

Magnetic field induced resistance properties at filling factor 5/2 consistent with non-Abelian e/4 quasiparticles in multiple sized interferometers

R. L. Willett, L. N. Pfeiffer, K. W. West

Non-Abelian e/4 quasiparticles at 5/2 filling factor in a correlated two-dimensional electron gas have a proposed specific property in an interference measurement of their edge pro…

Alternation and interchange of e/4 and e/2 period interference oscillations as evidence for filling factor 5/2 non-Abelian quasiparticles

R. L. Willett, L. N. Pfeiffer, K. W. West

It is a theoretical conjecture that 5/2 fractional quantum Hall state charge e/4 excitations may obey exotic non-Abelian statistics. In edge state interference these purported non-…

Measurement of filling factor 5/2 quasiparticle interference: observation of charge e/4 and e/2 period oscillations

R. L. Willett, L. N. Pfeiffer, K. W. West

A standing problem in low dimensional electron systems is the nature of the 5/2 fractional quantum Hall state: its elementary excitations are a focus for both elucidating the state…
