Comparing a traditional academic career path or BSD ('Big Shining Doctorate') with the real-life careers of four investigators. In a new perspective article, the four argue for more recognition of non ...

The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...

Researchers used the nonlinear optical response of atom-like defects in a diamond to build a tiny thermometer. This research may lead to temperature sensors that can work inside living cells and other ...

A research team has discovered a surprising phenomenon that could revolutionize how we think about signal amplification. Just two tiny vibrating units can, when connected with a delay, amplify their ...

The instability of Stokes waves (steady propagating waves on the surface of an ideal fluid with infinite depth) represents a fundamental challenge in the realm of nonlinear science. A team of ...
