We study the lateral Casimir force experienced by a particle that rotates near a planar surface. The origin of this force lies in the symmetry breaking induced by the particle rotation in the vacuum and thermal fluctuations of its dipole moment, and therefore, in contrast to lateral Casimir forces previously described in the literature for corrugated surfaces, it exists despite the translational invariance of the planar surface. Working within the framework of fluctuational electrodynamics, we derive analytical expressions for the lateral force and analyze its dependence on the geometrical and material properties of the system. In particular, we show that the direction of the force can be controlled by adjusting the particle-surface distance, which may be exploited as a new mechanism to manipulate nanoscale objects.

Researchers at the University of Pennsylvania have developed a new technique to study the surface of different types of glass. Using this technique, they discovered a surprising property of the top layer of glasses, which could pave the way to developing better glass materials.
The research was led by Yue Zhang, a graduate student in the Department of Chemistry in Penn's School of Arts & Sciences, and Zahra Fakhraai, assistant professor of chemistry. Zhang received an APS Padden Award for the research, which recognizes excellence in polymer physics research.
The distinction between crystals and liquids is that, while crystals are ordered and solid, liquids are disordered and can move around to fill whatever container they are in. But if one were to cool a liquid sufficiently, it would remain disordered while the motion of its molecules would slow down so much that it would seem solid. This is how amorphous materials such as glasses form.
Honey, for instance, is a liquid, but when it is refrigerated its properties become more like that of a solid.
