THE effect of the electric field upon spectral lines is a problem which has caused much discussion without being solved by experiment until to-day. Applying a very intense electric field in an ...

“The laser oscillator consists of a robust, self-standing, and deformable minute droplet that emits laser through Whispering-Gallery Mode resonance when optically pumped. The laser oscillation is ...

The discovery of the new vortex electric field in the twisted bilayer has also created a 2D quasicrystal, potentially enhancing future electronic, magnetic and optical devices.

Much like a precise engraving, the scientists used the tip of an atomic force microscope to apply a highly localized electric field to the material's surface, forming micrometric patterns with ...
