Fractional quantum Hall effect at the filling factor
Ken K. W. Ma, Michael R. Peterson, V. W. Scarola +1
The fractional quantum Hall (FQH) effect at the filling factor was discovered in GaAs heterostructures more than 35 years ago. Various topological orders have been proposed…
Half-filled 2D bilayers in a strong magnetic field: Revisiting the fractional quantum Hall effect
S. Das Sarma, Michael R. Peterson
We examine the quantum phase diagram of the fractional quantum Hall effect in the lowest Landau level in half-filled bilayer structures as a function of tunneling strength and laye…
Spontaneous Particle-Hole Symmetry Breaking in the Fractional Quantum Hall Effect
Michael R. Peterson, Kwon Park, S. Das Sarma
The essence of the fractional quantum Hall effect is believed to be well captured by the Moore-Read Pfaffian (or anti-Pfaffian) description. However, an important mystery r…
Finite Layer Thickness Stabilizes the Pfaffian State for the 5/2 Fractional Quantum Hall Effect: Wavefunction Overlap and Topological Degeneracy
Michael. R. Peterson, Th. Jolicoeur, S. Das Sarma
We find the finite-width, i.e., the layer thickness, of experimental quasi-two dimensional systems produces a physical environment sufficient to stabilize the Moore-Read Pfaffian s…
Orbital Landau level dependence of the fractional quantum Hall effect in quasi-two dimensional electron layers: finite-thickness effects
Michael R. Peterson, Th. Jolicoeur, S. Das Sarma
The fractional quantum Hall effect (FQHE) in the second orbital Landau level at filling factor 5/2 remains enigmatic and motivates our work. We consider the effect of the quasi-2D…
Reconstructing the electron in a fractionalized quantum fluid
Jainendra K. Jain, Michael R. Peterson
The low energy physics of the fractional Hall liquid is described in terms quasiparticles that are qualitatively distinct from electrons. We show, however, that a long-lived electr…
