Guest speaker Giovanni Vignale, professor of physics at the University of Missouri-Columbia, will present the “Many-Body Effects in Spintronics,” during a colloquium sponsored by the CSUF College of Natural Sciences and Mathematics and the Physics Department.

Spintronics, a new branch of electronics, attempts to create devices that exploit the spin of the electron to perform logical and memory operations. These devices operate on spin-polarized currents, which are much more strongly affected by electron-electron interactions than their unpolarized counterparts. In his talk, Vignale will show how the many-body correlation between electrons of opposite spin orientations leads to an unusual form of internal friction for spin-polarized currents — the spin Coulomb drag — that affects virtually all aspects of spin transport in metals and semiconductors.
