Abstract: We present a novel approach for characterizing the properties and performance of active matter in dilute suspension as well as in crowded environments. We use Super-Heterodyne Laser-Doppler-Velocimetry (SH-LDV) to study large ensembles of catalytically active… read more here.

Abstract: A striking abnormal harmonic is detected in the measurement signal spectrum of a heterodyne laser interferometer, which deviates from the conventional frequency-domain model. A nonlinearity model based on intermodulation is proposed to explain this abnormality… read more here.
