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…
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…
Jastrow-Luttinger Fractional Liquids
K. -V. Pham, M. Gabay, P. Lederer
In this paper, we present a description of Haldane's Luttinger liquid which parallels Laughlin's theory of the Fractional Quantum Hall (FQH) incompressible fluid, both exhibiting s…
Magneto-Roton Modes in the Ultra Quantum Crystal: Life and Death at Large Magnetic Field
Pascal Lederer, C. M. Chaves
The Ultra Quantum Crystal (UQC) phases observed in quasi-one-dimensional conductors of the Bechgaard salts family under magnetic field exhibit both Spin Density Wave order and a Qu…
