  • Title: Possible reentrance of the fractional quantum Hall effect in the lowest Landau level.
    Author: Goerbig MO, Lederer P, Morais Smith C.
    Journal: Phys Rev Lett; 2004 Nov 19; 93(21):216802. PubMed ID: 15601047.
    Abstract:
    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 composite fermions. The liquid phases have a lower energy than the competing solids around the electronic filling factors nu = 4/11,6/17, and 4/19 and may thus be responsible for the fractional quantum Hall effect at nu = 4/11. The alternation between solid and liquid phases when varying the magnetic field may lead to reentrance phenomena in analogy with the observed reentrant integral quantum Hall effect.
