Quantum plasmas. Quantum effects become important under extreme conditions, and a newly developing field of "quantum plasmas" is motivated by two different extremes for ionized systems. One is in very small electronic devises, where electrons carrying the currents become wave-like with a wavelength comparable with the size of the device. The other is in the extremely intense optical light spots now available by focusing high-power lasers. In this project we propose to take a leading role in the ....Quantum plasmas.
