Anomalous nematic states in half-filled Landau levels in tilted magnetic fields

ORAL

Abstract

In this talk we examine the effect of in-plane magnetic fields on anomalous nematic phases in half-field high Landau levels which are characterized by unexpected minima (maxima) in Rxx (Ryy) and plateau-like features in RH emerging at low temperatures. In particular, we have found that these features quickly disappear upon application of in-plane magnetic field, regardless of its orientation with respect to the native anisotropy axis, and that conventional quantum Hall stripe phase is restored.
