First 'heavy-fermion' material made in 2D

Physicists in Japan have created the first 2D "heavy-fermion" material – providing the best evidence yet that heavy fermions undergo a quantum phase transition. The material was made using molecular beam epitaxy (MBE), which also allowed the researchers to carry out the first systematic study of how the electronic properties of a heavy-fermion material change when it is made into layers just one molecule thick. The results could help physicists to understand why some other layered materials superconduct at relatively high temperatures.

It's a safe bet that the materials comprising the skin of a UFO are going to be highly advanced, layered metamaterials. This kind of fundamental materials research is heading us in that general direction.   To read the rest of the article, click here.
