Quantum Phases in Partially Filled Landau Levels
M. O. Goerbig, P. Lederer, C. Morais Smith
We compare the energies of different electron solids, such as bubble crystals with triangular and square symmetry and stripe phases, to those of correlated quantum liquids in parti…
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…
Comment faire fondre un cristal d'electrons bidimensionnel sous champ magnetique
M. O. Goerbig, P. Lederer, C. Morais Smith
C'est un phenomene connu de la vie quotidienne : si l'on augmente la temperature, la glace fond. Ceci est le paradigme d'une transition de phase solide-liquide, qu'on observe egale…
