Fractional quantum Hall effect without Landau levels
The quantum Hall effect (QHE) is the remarkable observation of quantized transport in two dimensional electron gases placed in a transverse magnetic field: the longitudinal resistance vanishes while the Hall resistance is quantized to a rational multiple of h/e2. The theory of the QHE is built largely around the special properties of single-particle free-electron states in a magnetic field—the ...

متن کاملFractional quantum Hall effect in the absence of Landau levels
It is well known that the topological phenomena with fractional excitations, the fractional quantum Hall effect, will emerge when electrons move in Landau levels. Here we show the theoretical discovery of the fractional quantum Hall effect in the absence of Landau levels in an interacting fermion model. The non-interacting part of our Hamiltonian is the recently proposed topologically non-trivi...
متن کاملPossible reentrance of the fractional quantum Hall effect in the lowest Landau level.
In the framework of a recently developed model of interacting composite fermions, we calculate the energy of different solid and Laughlin-type liquid phases of spin-polarized composite fermions. The liquid phases have a lower energy than the competing solids around the electronic filling factors nu = 4/11,6/17, and 4/19 and may thus be responsible for the fractional quantum Hall effect at nu = ...
متن کاملA First-Landau-Level Laughlin/Jain Wave Function for the Fractional Quantum Hall Effect.
We show that the introduction of a more general closed-shell operator allows one to extend Laughlin’s wave function to account for the richer hierarchies (1/3, 2/5, 3/7 . . . ; 1/5, 2/9, 3/13, . . . , etc.) found experimentally. The construction identifies the special hierarchy states with condensates of correlated electron clusters. This clustering implies a single-particle algebra within the ...
