The golden section found at the quantum level


31/10/2010

"Golden Section", equal to about 1.618, is found in many different aspects of our life, including biology, architecture, and the humanities.

But it is now known that this particular ratio also exists at the micro level. This discovery was made by researchers from Oxford and Bristol Universities, as well as from the laboratory Rutherford Appleton Laboratory, and from the German Research Center Helmholtz-Zentrum Berlin for Materials and Energy.

Their work, published in the journal Science, was devoted to the study of chains of bound molecules of cobalt niobate (CoNb2O6) width of only one molecule, in order to study the Heisenberg uncertainty principle. They applied a magnetic field accurately verified by an angle to the parallel spins of magnetic chains to bring more quantum uncertainty. Following the changes in the direction of the field, these small magnets were resonate like a guitar string.

By molecules of cobalt niobate shot neutrons to highlight the resonant notes. "We found a series of resonant notes: The first two notes are in amazing proportions relative to each other. Their frequencies (pitch) are correlated as 1,618 - which is the golden ratio famous from art and architecture," - wrote in a press release, the head of research Dr. Radu Colden from Oxford University. "This is a clear example of how beautiful are the properties of quantum systems, hidden symmetry."

Dr. Alan Tennant, who led the research team from Berlin, said: "These findings may encourage physicists to the conclusion of a special internal structure of the quantum world at the atomic level. Similar surprises may await researchers in the study of other materials in the quantum critical state."
