Edge states of composite fermions

Physical Review B, 1994
We investigate the edge structure of a system of composite fermions confined in a wire. Using the composite fermion picture of the fractional quantum Hall effect, we have studied the electronic edge structure of different fractional quantum Hall liquids.

Geometrical effect of composite fermions

Physical Review B, 1995
According to recent theoretical and experimental work, the two-dimensional interacting electron gas in a strong magnetic field can be well described in terms of composite fermions for which the net magnetic field vanishes at a filling factor 1/2. We present a semiclassical theory of a geometrical effect of composite fermions that manifests itself by a ...

Incompressible composite fermion liquids

Physica E: Low-dimensional Systems and Nanostructures, 2008
The "second generation" fractional quantum Hall states containing a partially filled composite fermion (CF) Landau level (LL) are studied theoretically. The role of the unique form of the CF-CF interaction in the incompressibility of the underlying quantum electron liquid is explained. In particular, the two- and three-body CF correlation functions for

Magnetooptics of composite fermions

Physics-Uspekhi, 2001
The Fermi energy and the Zeeman splitting of composite fermions are measured from the temperature dependence of the electron spin polarization at v = 1/2. We demonstrate that the Zeeman splitting of composite fermions is enhanced by a factor of 2.5 due to the interaction between CFs.

Composite fermions pair up

Nature, 2000
In the fractional quantum Hall effect, seen when a two-dimensional conductor is placed in a strong magnetic field at low temperatures, electrons can bind to magnetic vortices to form ‘composite fermions’. Under certain conditions these strange particles can pair up to form a composite fermion ‘superconductor’.
