Electron spin filtering in ferromagnet/semiconductor heterostructures
(2003)Circularly polarized light was used to generate spin-polarized electrons at room temperature in ferromagnet (FM)/GaAs Schottky diode structures. A change in the helicity-dependent photocurrent was obtained when the ...

A Multiplexed Bragg Grating Fiber Laser Sensor System
(1993)A technique for multiplexing Bragg gratings in a fiber laser arrangement is described. This technique has successfully been used to multiplex two and three Bragg gratings with very little crosstalk. The Bragg grating laser ...

Non-peturbative density expansions for extended Coulomb systems
(2000)We present a general non-perturbative argument that combines the Pauli and virial theorems for a multicomponent translationally invariant Coulombic system of fermions at zero temperature, and which by an iteration procedure ...

θ Dependence of 4D SU(N) gauge theories at finite temperature
(Proceedings of Science (PoS), 2013)We report a study of the dependence of 4D SU(N) gauge theories on the topological θ term at finite temperature, and in particular in the large-N limit. We show that theθ dependence drastically changes across the deconfinement ...
