The electronic Barnett effect, first observed by Samuel Barnett in 1915, is the magnetization of an uncharged body as it is spun on its long axis. This is caused by a coupling between the angular momentum of the electronic ...
Current technologies for information transfer and processing are challenged by fundamental physical limits. The more powerful they become, the more energy they need, and the more heat is released to the environment. Also, ...
