The electrical resistance of a metal is caused by electrons being scattered from impurities in the material’s atomic lattice or from lattice vibrations called phonons. However, it is not affected by ...

Physicists report new insights into the behavior of electrons on the surface of a topological insulator, a class of material with unique properties that challenge some of the oldest laws of physics.

A team of physicists is reporting the first success from a three-year effort to emulate superconductors with ultracold atoms trapped in grids of laser beams. A new study describes how the group ...

CHESTNUT HILL, MA (October 25, 2012) – In the relatively new scientific frontier of topological insulators, theoretical and experimental physicists have been studying the surfaces of these unique ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...

Researchers at the University of Chicago’s Pritzker School of Molecular Engineering (PME) have discovered a new material, MnBi6Te10, which can be used to create quantum highways along which electrons ...
