Study from the Institute for Applied Physics published in “Physical Review Letters”

Research teams at the Institute for Applied Physics at TU Darmstadt and the RPTU Kaiserslautern-Landau have demonstrated for the first time that, disordered atoms in permanent motion can nonetheless jointly emit directed light into a single direction despite neither the atoms nor their surrounding environment exhibiting a distinguishing directionality. Furthermore, the magnitude of this asymmetry can be controlled.

TU Darmstadt-led study published in “Nature Communications”

Tiny manufacturing imperfections in optical components normally go unnoticed. Yet they can alter light in surprisingly significant ways. An international research team led by TU Darmstadt has shown that such imperfections can affect not only polarization – the direction in which light oscillates – but also the spatial shape of a light beam. The findings, now published in “Nature Communications”, could help make sensitive optical measurements even more precise in the future.
