Physics provides daily online-only news and commentary about a selection of papers from the APS journals collection. It is aimed at the reader who wants to keep up with highlights of physics research with explanations that don’t rely on complex technical detail.

The category Physics: focus stories features only a few number of articles each week selected among the set of articles published on all the APS journals.
Research articles that have an interdisciplinary character are usually selected, and their explanations are geared toward students and non-experts. Features are written by a journalist for an audience with a general interest in physics.

We experimentally demonstrate a microscopic engine powered by the local reversible demixing of a critical mixture. We show that, when an absorbing microsphere is optically trapped by a focused laser beam in a sub-critical mixture, it is set into rotation around the optical axis of the beam because of the emergence of diffusiophoretic propulsion. This behavior can be controlled by adjusting the optical power, the temperature, and the criticality of the mixture.

Falko Schmidt starts his PhD

Falko Schmidt starts his PhD at the Physics Department of the University of Gothenburg on 1 January 2017.

He has a Master degree from the Physics Department of Leipzig University with a Master thesis on the realisation of a microscopic critical engine.

He will now work on his PhD thesis on the experimental study of critical fluctuations and critical Casimir forces.
