Glass transition meets Fickian-non-Gaussian Diffusion

Glass transition is a Grand Challenge in condensed matter physics and still reveals surprises, despite decades of intense research. For instance, diffusion in glassy liquids was until now thought to be qualitatively similar ...

Graphene crystals grow better under copper cover

An approach that produces single-crystal graphene sheets on large-scale electrically insulating supports could help with the development of next-generation nanomaterial-based devices, such as very light and thin touchscreens, ...

Physicists created a microlaser emitting two circular beams

Scientists from the University of Warsaw, the Military University of Technology and the University of Southampton presented a new type of tunable microlaser emitting two beams. "These beams are polarized circularly and directed ...

Tomographic measurement of dielectric tensors

A research team reported the direct measurement of dielectric tensors of anisotropic structures including the spatial variations of principal refractive indices and directors. The group also demonstrated quantitative tomographic ...
