Oscillations in immiscible liquids due to persistent currents — •Frederic Folz, Ayoub Elyaagoubi, Albrecht Ott, and Giovanna Morigi — Universität des Saarlandes

Absorption spectroscopy exhibits a noisy absorption pattern in samples of colloidal gold at marginal stability [1]. This might be the signature of an oscillatory behavior. Here, we discuss a theoretical model that traces these oscillations back to agglomeration and sedimentation processes, given a persistent influx of molecules. We analyse the results in relation to the experimental findings.
