Solid-state physics: Join the dots
Galina Khitrova1 & H. M. Gibbs1
Abstract
A new variation on an old theme in atomic physics, a spectral distortion known as the Fano effect, has been revealed — not in an atom, but in an artificial nanostructure known as a quantum dot.
The Fano effect is a quantum-mechanical interference phenomenon characterized by an asymmetrical broadening of spectral lines that pops up all over the place when certain materials absorb light. In 1981, it was predicted1 that using light from a strong resonant laser beam would completely alter the spectrum of the Fano effect.
