A new picture of both integer and fractional incompressible quantum Hall fluids as fluids carrying a electric quadrupole is introduced. This clarifies their geometric properties, provides a generic expression for Hall viscosity, and allows removal of the ingredient of continuous rotational symmetry (absent when electrons move in a crystalline background) from their description.

  1. Spin fractionalization at the edge of quantum Hall fluids induced by bulk quasiparticles

    cond-mat.str-el 2024-12 conditional novelty 6.0 of 10

    A straight-edge spin observable is defined for quantum Hall fluids and shown to fractionalize with bulk quasiparticles through a reference-dependent density dipole moment.
