In a crystal, facets refer to the planes composed of different atom arrangements. In nature, crystals tend to form a polyhedral shape as a result of multi-facets, and realizing single-facet in a ...

A new study of ultracold atomic gases finds a quantum anomaly: strongly interacting particles breaking classical symmetry in a 2-D Fermi gas. A FLEET study of ultracold atomic gases -- a billionth the ...
