where μ = (μ R + μ L)/2 and T are the chemical potential and the temperature, and v is the Fermi velocity. The chiral anomaly of quantum electrodynamics dictates that the parallel external electric ...
UPTON, NY--Scientists at the U.S Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University have discovered a new way to generate very low-resistance electric current in a ...
The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of ...
