(Phys.org) —In order to study many complex phenomena, physicists seek to isolate them in potential wells or boxes with easily described forms and boundary conditions. These features in turn dictate various behaviors of ...
(Phys.org) —The new material's artificial "atoms" are designed to work with a broad range of light frequencies. With adjustments, the researchers believe it could lead to perfect microscope lenses or invisibility cloaks.
