A Systematic Improvement for Calculation to Conductivity in Anomalous Propagation of Surface Acoustic Wave at $ν={1/2}$

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/28024We report a systematic improvement to calculate the conductivity which associates to the anomaly of the propagation of surface acoustic waves at $ν={1/2}$ above a two-dimensional electron gas. We try to resolve the discrepancy between theoretical and experimental values for the magnitude of $σ_{xx}(q)$ by considering the contribution to the response functions from the self-interaction among the Chern-Simons gauge fluctuations.4 pages, revtex, 2 figuresCondensed MatterA Systematic Improvement for Calculation to Conductivity in Anomalous Propagation of Surface Acoustic Wave at $ν={1/2}$text
