Space-time aspects of quasiparticle propagation

The authors discuss how spin-charge separation is realized in a simple double-layer geometry, how mass renormalization affects time-of-flight in compressible Hall states, and how quantum drifts can reveal the effective charge, mass and quantum statistics in incompressible Hall states. They also discuss the possibility of observing the effect of fractional statistics directly in scattering. Finally they propose that, as a result if incompressibility and reflecting the fundamental charge-flux relation, charged probes induce macroscopic rotation of Hall fluids
