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…
Scaling Approach to the Phase Diagram of Quantum Hall Systems
M. O. Goerbig, C. Morais Smith
We present a simple classification of the different liquid and solid phases of quantum Hall systems in the limit where the Coulomb interaction between the electrons is significant,…
Magnetoroton instabilities and static susceptibilities in higher Landau levels
M. O. Goerbig, C. Morais Smith
We present analytical results concerning the magneto-roton instability in higher Landau levels evaluated in the single mode approximation. The roton gap appears at a finite wave ve…
