Most of us don’t think of atoms as having their own unique vibrations, but they do. In fact, it’s a feature so fundamental to nature’s building blocks that a team of University of Washington researchers recently observed and used this phenomenon in their research study. By studying the light atoms emitted when stimulated by a laser, they were able to detect vibrations sometimes referred to as atomic “breathing.”

    Maybe you should have read the article: “By applying a precise pulse of laser light to one of the quantum dots, an electron is knocked away from the tungsten diselenide atom’s nucleus. This briefly creates a quasiparticle known as an exciton. This exciton is composed of the negatively charged electron and the corresponding positively charged hole in the opposite sheet. Because they are strongly bound, the electron quickly returns to the atom. When it does this, it releases a single photon encoded with very specific quantum information.”
