Non-Universal Fractional Quantum Hall States in a Quantum Wire

The ground state as well as low-lying excitations in a 2D electron system in strong magnetic fields and a parabolic potential is investigated by the variational Monte Calro method. Trial wave functions analogous to the Laughlin state are used with the power-law exponent as the variational parameter. Finite size scaling of the excitation energy shows that the correlation function at long distanc...

High-temperature fractional quantum Hall states.

We show that a suitable combination of geometric frustration, ferromagnetism, and spin-orbit interactions can give rise to nearly flatbands with a large band gap and nonzero Chern number. Partial filling of the flatband can give rise to fractional quantum Hall states at high temperatures (maybe even room temperature). While the identification of material candidates with suitable parameters rema...

Exclusion statistics for fractional quantum Hall states on a sphere

We discuss exclusion statistics parameters for quasiholes and quasielectrons excited above the fractional quantum Hall states near ν = p/(2np + 1). We derive the diagonal statistics parameters from the (“unprojected”) composite fermion (CF) picture. We propose values for the off-diagonal (mutual) statistics parameters as a simple modification of those obtained from the unprojected CF picture, b...

Edge reconstruction in fractional quantum Hall states

The nature of edge reconstruction in the quantumHall e ect (QHE) and the issue of where the current flows have been debated for years.Moreover, the recent observation of proliferation of ‘upstream’ neutral modes in the fractional QHE has raised doubts about the present models of edge channels. Here, we present a new picture of the edge reconstruction in two of the holeconjugate states. For exam...
