An emitter near a surface induces an image dipole that can modify the observed emission intensity and radiation pattern. These image-dipole effects are generally not taken into account in ...

Long thought to be a simple speck of negative charge, the humble electron may be hiding one more surprise in its depths. The electron was the first fundamental particle discovered. It was the first to ...

Physicists in the US have created an ultracold gas of molecules with “adjustable” dipole moments. The experiment, which is the first to study the effect of long-range dipole interactions in an ...
