Composite Fermions in Fractional Quantum Hall Systems

The composite Fermion (CF) picture offers a simple intuitive way of understanding many of the surprising properties of a strongly interacting twodimensional electron fluid in a large magnetic field. The simple way in which the mean field CF picture describes the low lying bands of angular momentum multiplets for any value of the applied magnetic field is illustrated and compared with the result...

Composite Fermions Phenomenology in Quantum Hall Effect

An effort is made to understand the phenomenological composite fermion model of the quantum Hall effect. The odd denominators are composed by adding ±1 to the even numbers, 2, 4, 6, and 8. Although the denominators are phenomenologically made to agree with the experimental data, the physics of the CF model ,i.e., the even flux quanta attachment to the electron is found to be incorrect. keshav@m...

Second Generation of Composite Fermions and the Self-Similarity of the Fractional Quantum Hall Effect

A recently developed model of interacting composite fermions, is used to investigate different composite-fermion phases. Their interaction potential allows for the formation of both solid and new quantum-liquid phases, which are interpreted in terms of second-generation composite fermions and which may be responsible for the fractional quantum Hall states observed at unusual filling factors, su...

Composite fermions and Landau-level mixing in the fractional quantum Hall effect.

The reduction of the energy gap due to Landau level mixing, characterized by the dimensionless parameter λ = (e/ǫl0)/h̄ωc, has been calculated by variational Monte Carlo for the fractional quantum Hall effect at filling fractions ν = 1/3 and 1/5 using a modified version of Jain’s composite fermion wave functions. These wave functions exploit the Landau level mixing already present in composite f...

Structures for interacting composite fermions: Stripes, bubbles, and fractional quantum Hall effect

Much of the present day qualitative phenomenology of the fractional quantum Hall effect can be understood by neglecting the interactions between composite fermions altogether. For example, the fractional quantum Hall effect at n5n/(2pn61) corresponds to filled composite-fermion Landau levels, and the compressible state at n51/2p to the Fermi sea of composite fermions. Away from these filling fa...
