Spin-excitations of the quantum Hall ferromagnet of composite fermions
R. L. Doretto, M. O. Goerbig, P. Lederer +2
The spin-excitations of a fractional quantum Hall system are evaluated within a bosonization approach. In a first step, we generalize Murthy and Shankar's Hamiltonian theory of the…
Possible Reentrance of the Fractional Quantum Hall Effect in the Lowest Landau Level
M. O. Goerbig, P. Lederer, C. Morais Smith
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 compo…
On the self-similarity in quantum Hall systems
M. O. Goerbig, P. Lederer, C. Morais Smith
The Hall-resistance curve of a two-dimensional electron system in the presence of a strong perpendicular magnetic field is an example of self-similarity. It reveals plateaus at low…
Competition between quantum-liquid and electron-solid phases in intermediate Landau levels
M. O. Goerbig, P. Lederer, C. Morais Smith
On the basis of energy calculations we investigate the competition between quantum-liquid and electron-solid phases in the Landau levels n=1,2, and 3 as a function of their partial…
Second Generation of Composite Fermions in the Hamiltonian Theory
M. O. Goerbig, P. Lederer, C. Morais Smith
In the framework of a recently developed model of interacting composite fermions restricted to a single level, we calculate the activation gaps of a second generation of spin-polar…
Microscopic Theory of the Reentrant IQHE in the First and Second Excited LLs
M. O. Goerbig, P. Lederer, C. Morais Smith
We present a microscopic theory for the recently observed reentrant integral quantum Hall effect in the n=1 and n=2 Landau levels. Our energy investigations indicate an alternating…
