Spin-orbit coupling in mercury telluride leads to the appearance of a version of this effect that does not require the presence of a magnetic field.
Composite Fermion theory was originally used to explain the Moore-Read states associated with this effect. Mele and Kane tied a version of this effect to time-reversal-symmetry-protected edge states in topological insulators. Spin-orbit coupling in mercury telluride leads to the appearance of a version of this effect that does not require the presence of a magnetic field. The (*) Laughlin wavefunction describes systems subject to this effect, whose strength is modified by a filling factor. Klaus von Klitzing won a Physics Nobel for his observations of this effect's creation of quantized conductance values that are multiples of e squared over h. For 10 points, name this quantum-scale version of a classical effect in which a potential difference is produced perpendicular to both an applied magnetic field and a current.
