In the home, the lab and the factory, electric fields control technologies such as Kindle displays, medical diagnostic tests ...

I hope that you are never in a situation in which you are in danger from a downed, but live, power line. However, if that ever happens, the recommended safety procedure is to move away with tiny, ...

The charge-carrier density—or equivalently, the Fermi energy—strongly controls phase transitions in correlated systems. Traditionally, charge-carrier density can be controlled by doping, that is, by ...

Electromagnetism is a simple example of a gauge theory where the underlying potentials (the vector and scalar potentials) are defined only up to a gauge choice. The vector potential generates magnetic ...
