A team of researchers in the Republic of Korea, the U.S., Brazil, Indonesia and the U.K. have recently carried out a direct search for inelastic boosted dark matter (IBDM) using a terrestrial detector. Their study, published ...
New photonic tools for medical imaging can be used to understand the nonlinear behavior of laser light in human blood for theranostic applications. When light enters biological fluids it is quickly scattered, however, some ...
Light-by-light scattering is a very rare phenomenon in which two photons interact, producing another pair of photons. This process was among the earliest predictions of quantum electrodynamics (QED), the quantum theory of ...

For the Kerker effect to occur, particles need to have electric and magnetic polarizabilities of the same strength. This, however, is very challenging to achieve, as magnetic optical resonances in small particles are relatively ...
When you light up a metal nanoparticle, you get light back. It's often a different color. That's a fact—but the why is up for debate.
