Amazingly: Sound of an Atom Captured by Scientists

A team of scientists have ‘communicated’ with an artificial atom by the way of SOUND. The atom in question was designed to absorb and emit sound energy. When the atom was hit with sound waves, it emitted something similar. The sound of the atom was described to be like a D note.


Nature has always had hidden mysteries embedded in its make-up, as if, to ignite our curiosity further, baiting us to go after them in order to unveil them. We yearn to understand the reasons behind the being of everything we perceive in our environment, and, we crave to see through those things that our eyes cannot capture. We cannot directly view the tiniest particles in our environment, but our curiosity-driven brain has led us to discover the atom, and further allowing us to break through it to find even more minute particles. The atom, however small it is, wraps in itself layers and layers of mysteries. Can the atom reveal itself to us? Recently, a group of researchers from the Chalmers University of Technology have attempted to ‘communicate’ with an artificial atom by making use of sound as medium: ‘talking and listening’ to an atom. The scientific paper is to be published in the journal Science.

The team of scientists have made acoustic waves interact with an artificial atom. “We have opened a new door into the quantum world by talking and listening to atoms,” stated Per Delsing, one of the scientists of the group. The artificial atom that they worked with was engineered such that it was able to absorb and release energy in the form of sound – an experiment being a first of its kind. Previous works have dealt with atoms and light, the techniques of which are easier to manipulate. The Chalmers researchers have, however, opted to be more ambitious and took on the challenging task of using sound.

Theories expound that the sound from the atom is composed of quantum particles – the sound of which would be the weakest to be detected. Bear in mind, reader, that sound travels slower than light. This slow speed implies that it will be easier to control the quantum particles as they move; light, on the other hand, travels 100 000 times faster, which makes the same task much more difficult.

Now, how did the artificial sound like? Pretty much like a D note, the difference, however, being that it is too high-pitched to be captured by the human ears.
