Estimating a mass for a potentially hazardous asteroid (PHA) is perhaps the single most important thing to understand about it, after its trajectory. Actually doing so isn’t easy though, as the mass for objects in the tens to hundreds of kilometers in size are...
A study from the Research Center for Materials Nanoarchitectonics (MANA) has uncovered a theoretical mechanism showing how the electronic band structures of strongly correlated insulators can be reshaped by spin and charge perturbations, opening up new possibilities...
“Glass” has a unique and distinct meaning in physics—one that refers not just to the transparent material we associate with window glass. Instead, it refers to any system that looks solid but is not in true equilibrium and continues to change extremely...
Multiphoton microscopy is used in biomedical research to study cells and tissues. Today, so-called two-photon microscopy is used to study processes within cells, but the technique has limitations in terms of image resolution. Four-photon microscopy provides images...
Physicists and chemists at Heidelberg University have realized a photonic microchip that is driven by light just as easily as electronic components via a “plug.” Their development could serve as the basis for fast and cost-effective production of photonic...
