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 ...

Dipole toroidal modes are a unique set of excitations that are predicted to occur in various physical systems, ranging from atomic nuclei to metamaterials. What characterizes these excitations, or ...

New research challenges the standard cosmological model, suggesting that the universe may be asymmetric or lopsided rather than uniform in all directions.

The most precise measurement yet of the electron’s shape casts doubt on ideas such as supersymmetry that predict a zoo of undetected particles in the universe Scientists are unanimous that their ...
