The problem is efficiency. Maxwell's equations are completely linear, so nonlinear optics relies entirely on materials with nonlinear response to optical fields. Unfortunately these responses deviate ...

“Mathematics is the art of reducing any problem to linear algebra.” This is a quote often attributed to William Stein, a former mathematics professor at the University of Washington, now the lead ...

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 ...

Journal of Nonlinear Waves is the home for the field of nonlinear wave phenomena, broadly defined. It publishes authoritative articles on theoretical and computational aspects of nonlinear waves ...

How is that doubling and not squaring? Is that a domain-specific use of the word doubling that's different from the everyday one? Normally "doubling" would be the function f(x) = 2x. Click to expand..

A team of researchers at Nagoya University has discovered something surprising. If you have two tiny vibrating elements, each one barely moving on its own, and you combine them in the right way, their ...
