Möbius Symmetry in Metamaterials

July 3, 2012
rtificial molecules can possess a new kind of symmetry that cannot be found in natural molecules. This image describes a hyperspace Möbius machine that transforms ordinary bezene molecules into metamolecules with Möbius symmetry--the topological phenomenon that yields a half-twisted strip with two surfaces but only one side. For years, scientists have been searching for an example of Möbius symmetry in natural materials without any success. But a team of researchers, led by Xiang Zhang of the U.S. Department of Energy's Lawrence Berkeley National Laboratory (LBNL) and a professor at the University of California, Berkeley, discovered Möbius symmetry in metamaterials. Metamaterials are materials engineered from artificial atoms and molecules with electromagnetic properties that arise from their structure rather than their chemical composition.
