Coplesit de creatia lui Dumnezeu – Sunetul unui atom – Scientists capture the sound of an atom, open a new door into the quantum world

De la Ziarul Adevarul –

Cercetătorii suedezi au reuşit să capteze sunetul unui atom, care aparent este nota Re, iar descoperirea, spun aceştia, deschide o „nouă poartă către lumea cuantică prin comunicarea cu atomii“, potrivit unui studiu prezentat de huffingtonpost.com.

Pentru acest studiu, cercetătorii au construit un atom artificial de 0,01 milimetri şi l-au plasat la capătul unui material superconductor. Apoi au ghidat undele sonore pe suprafaţa materialului, au colectat sunetul din atom şi l-au înregistrat cu ajutorul unui microfon foarte mic plasat la celălalt capăt al materialului.

Sunetul era o „notă Re“ cu 20 de octave mai sus decât cea mai înaltă notă produsă de un pian, iar urechea umană nu îl poate detecta.Citeste mai mult: adev.ro/nbuhws

Scientists Have Captured The Sound Of An Atom

 Scientists have captured the sound of a single atom by measuring its vibrations. We can’t hear it, but it’s reportedly the faintest sound possible.

London: For the first time, scientists have used sound to ‘talk’ to an artificial atom, demonstrating a curious phenomenon in quantum physics that sees sound waves take on the role of light.

The interaction between atoms and light is well known and has been studied extensively in the field of quantum optics. However, to achieve the same kind of interaction with sound waves has been a more challenging undertaking. The researchers at the Chalmers University of Technology in Sweden have now succeeded in making acoustic waves couple to an artificial atom.

„We have opened a new door into the quantum world by talking and listening to atoms,” said Per Delsing, head of the experimental research group.

The frequency used in the experiment is 4.8 gigahertz, close to the microwave frequencies common in modern wireless networks. In musical terms, this corresponds approximately to about 20 octaves above the highest note on a grand piano. The study appears in the journal Science.
