A team of researchers affiliated with a host of institutions in Japan and one in the U.K has observed Fermi pockets during experiments with a five-layered cuprate, confirming theories. In their paper published in the journal ...
To understand the behavior of quantum particles, imagine a pinball game—but rather than one metal ball, there are billions or more, all ricocheting off each other and their surroundings.
