Puzzling Electrons behavior in new metamaterials

A weird behavior of the electrons has been observed while studying new kind of crystal. According to the observation with a special scanning tunneling microscope, the electrons with a peculiar momentum sink in the material layer to appear on the other side.

New research from Princeton University demonstrates the bizarre movement of electrons through a novel material called a Weyl semi-metal. The image shows a schematic of the connections at special values of electron momentum, which come in pairs and are called Weyl points (red and blue dots). An electron that leaves the surface on a red point can return through its partner blue point, and vice versa. This bizarre behavior is due to the 'topological'connections through the bulk of the material. Credit: Yazdani et al., Princeton University.
