We revisit this effect in gold, a canonical Drude metal. We discover that the signal for p- polarized illumination in ambient air is affected in both sign and magnitude by adsorbed molecules, opening previous measurements for reinterpretation. Further, we show that the intrinsic sign of the photon-drag effect is contrary to the prevailing intuitive model…</p><p><a href="https://hackerpaper.kaipfister.de/p/1812.01673/">Paper and discussion history</a>.
