ONE-COMPONENT TO 2-COMPONENT TRANSITION OF THE NU=2 3 FRACTIONAL QUANTUM HALL-EFFECT IN A WIDE QUANTUM-WELL INDUCED BY AN INPLANE MAGNETIC-FIELD/

The nu= 2/3 fractional quantum Hall effect (FQHE) in a wide, single qu antum well subject to tilted magnetic fields makes a one-component to two-component transition induced by the in-plane component of the magn etic field. To analyze the experimental data we make a self-consistent , local-density-approximation calculation of the electronic structure of the wide quantum well in tilted magnetic fields. Our results are qu antitatively consistent with earlier experimental work on the density driven one-component to two-component FQHE transition in this system.
