Mass renormalization impacts time-of-flight measurements

Quantum drifts reveal effective charge, mass, and statistics

Abstract

Highly correlated states of electrons are thought to produce quasiparticles with very unusual properties. Here we consider how these properties are manifested in space-time propagation. Specifically, we 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. We also discuss the possibility of observing the effect of fractional statistics directly in scattering. Finally we propose that, as a result of incompressibility and the fundamental charge-flux relation, charged probes induce macroscopic, measurable rotation of Hall fluids.
