Ugo Fano

Ugo Fano was an Italian-American physicist renowned for his work in quantum mechanics and atomic physics. He made significant contributions to understanding how atoms absorb and emit light, particularly through the discovery of Fano resonances—an elegant way to describe how atomic energy states interact with each other and with electromagnetic waves. These insights help scientists interpret complex spectra in areas like nuclear physics and materials science. Fano’s work provides a deep understanding of the quantum behavior of particles, influencing various fields including laser development and nanotechnology.
