Quantum electrodynamics, a school of quantum mechanics, is the best-tested theory in physics. It describes all electrical and magnetic interactions of light and matter. In the macroscopic world, ...

Scientists have created the first real-time 3D simulations of how lasers alter the quantum vacuum. Using cutting-edge computational modeling, scientists from the University of Oxford, in collaboration ...

Physicists have found a radical new way confine electromagnetic energy without it leaking away, akin to throwing a pebble into a pond with no splash The theory could have broad ranging applications ...

The Nobel Prize in Physics was awarded to three scientists on Tuesday for discovering that a bizarre barrier-defying ...

The optical properties of metallic nanoparticles with nanometre dimensions exhibit features that cannot be described by classical electrodynamics. In this quantum size regime, the near-field ...

The 2025 Nobel Prize in physics honors three quantum physicists—John Clarke, Michel H. Devoret and John M. Martinis—for their ...

Any help/explanation on how to solve these would be appreciated. I've sadly forgotten most of the physics I learned in college, at least the quantitative stuff.<BR><BR>1. The two conducting rails in ...
