Valley Stoner instability of the composite Fermi sea
We study two-component electrons in the lowest Landau level at total filling factor ν[subscript T] = 1/2 with anisotropic mass tensors and principal axes rotated by π/2 as realized in aluminum arsenide (AlAs) quantum wells. Combining exact diagonalization and the density matrix renormalization group...
