Morphing of 2D Hole Systems at ν=3/2 in Parallel Magnetic Fields: Compressible, Stripe, and Fractional Quantum Hall Phases

A transport study of two-dimensional (2D) holes confined to wide GaAs quantum wells provides a glimpse of a subtle competition between different many-body phases at Landau level filling \nu=3/2 in tilted magnetic fields. At large tilt angles (\theta), an anisotropic, stripe (or nematic) phase replaces the isotropic compressible Fermi sea... Show more
