We provide numerical evidence that a p(x)-ip(y) paired Bonderson-Slingerland (BS) non-Abelian hierarchy state is a strong candidate for the observed ν=12/5 quantum Hall plateau. We confirm the existence of a gapped incompressible ν=12/5 quantum Hall state with shift S=2 on the sphere, matching that of the BS state. The exact ground state of the Coulomb interaction at S=2 is shown to have a large overlap with the BS trial wave function. Larger overlaps are obtained with BS-type wave functions…

Competing states for the fractional quantum Hall effect in the 1/3-filled second Landau level

In this work, we investigate the nature of the fractional quantum Hall state in the 1/3-filled second Landau level (SLL) at filling factor $\nu=7/3$ (and 8/3 in the presence of the particle-hole

Stability of the k = 3 Read–Rezayi state in chiral two-dimensional systems with tunable interactions

The k = 3 Read–Rezayi (RR) parafermion quantum Hall state hosts non-Abelian excitations which provide a platform for universal topological quantum computation. Although the RR state may be realized

Non-Abelian fractional quantum Hall state at 3/7 -filled Landau level

We consider a non-Abelian candidate state at filling factor $\nu=3/7$ state belonging to the parton family. We find that, in the second Landau level of GaAs (i.e. at filling factor $\nu=2+3/7$), this

Fractional quantum Hall effect in semiconductor systems

The fractional quantum Hall (FQH) effect refers to the strongly-correlated phenomena and the as- sociated quantum phases of matter realized in a two-dimensional gas of electrons placed in a large

Bipartite composite fermion States.

This approach gives accurate approximations for the exact Coulomb ground state at 2+3/5 and 2+4/7 and is thus a promising candidate for the observed fractional quantum Hall states at the hole conjugate fractions.

Enigmatic 12/5 fractional quantum Hall effect

We numerically study the fractional quantum Hall effect at filling factors $\nu=12/5$ and 13/5 (the particle-hole conjugate of 12/5) in high-quality two-dimensional GaAs heterostructures via exact

Parton construction of a wave function in the anti-Pfaffian phase

In this work we propose a parton state as a candidate state to describe the fractional quantum Hall effect in the half-filled Landau level. The wave function for this parton state is

Microscopic computations in the fractional quantum Hall effect

The microscopic picture for fractional quantum Hall effect (FQHE) is difficult to work with analytically for a large number of electrons. Therefore to make predictions and attempt to describe

Interacting composite fermions: Nature of the 4/5, 5/7, 6/7, and 6/17 fractional quantum Hall states

Numerical studies by W\'ojs, Yi, and Quinn have suggested that an unconventional fractional quantum Hall effect is plausible at filling factors $\ensuremath{\nu}=1/3$ and 1/5, provided the
