We discuss the composite fermion pairing state in bilayer quantum Hall systems, After evaluation of the range of the interlayer separation in which the quantum Hall state is stabilized, we discuss the effect of interlayertunneling on the composite fermion pairing state at v= ½. We show that there is a cusp at the transition point between the Halperin (3,3,1) state and the Pfaffian state. 
Spin singlet excitons of composite fermions
Interacting electrons in two degenerate Landau levels with opposite spins at total filling factor 1 are considered. Using the Chern-Simons gauge transformation, the system is mapped to compositeExpand
Ground states of interacting composite fermions with spin at total filling factor one
The effects of interactions in a 2D electron system in a strong magnetic field of two degenerate Landau levels with opposite spins and at filling factors 1/2 are studied. Using the Chern-Simons gaugeExpand
Phase transitions in single layer and bilayer quantum Hall ferromagnets
A remotely doped GaAs wide quantum well (WQW) of 77 nm width is used to explore ferromagnetic phase transitions (FPTs), which occur due to crossings of Landau levels (LLs), using magneto-transport atExpand
