Integral and fractional quantum Hall Ising ferromagnets
We compare quantum Hall systems at filling factor 2 to those at filling factors 2/3 and 2/5, corresponding to the exact filling of two lowest electron or composite fermion (CF) Landau levels. The two
Transport gap in a v=1/3 quantum Hall system: a probe for skyrmions
The dependence of the activated gap on magnetic field is studied for the fractional filling factor~1/3. By comparing the experimental results with results from exact diagonalization calculations we

This work provides a theory of the general structure of mixed-spin fractional quantum Hall states, which are relevant at low magnetic fields. This, in particular, leads to a microscopic description
LETTER TO THE EDITOR: Spin-dependent fractional QHE states in the N=0 Landau level
Spin assignments of fractional QHE states in the N=0 Landau level are determined from finite-size calculations of the Coulomb energy. There is a spin-unpolarised ground state at 2/3 filling, with

Fractional statistics and anyon superconductivity
The occurrence of fractional statistics has been discovered in more and more quantum field theory models, including some of the most geometrical and canonical ones. In a remarkable case, the

TLDR
Within the random-phase approximation a new, low-lying, diffusive mode, not present in the \ensuremath{\nu}=1/2 single-layer system, is found, which leads to more singular low-energy scattering and an attractive pairing interaction between fermions in different layers which grows stronger as the layer spacing is decreased.

TLDR
It is proposed that the fractional quantum Hall effect of electrons can be physically understood as a manifestation of the integer quantumHall effect of composite fermionic objects consisting of electrons bound to an even number of flux quanta.
HEURISTIC PRINCIPLE FOR QUANTIZED HALL STATES
It is argued that the incompressibility of fractional quantized Hall states, and the qualitative form of their wavefunction, can be understood by an argument based on adiabatic localization of

TLDR
Spin configurations of fractions zl\ensuremath{\nu}l2 are examined by angular and n-dependent activation studies to quantify a dramatic difference between (4/3 and (5/3) states consistent with assignments.
