Anyone for Anyons?

Researchers have demonstrated that a strange type of quantum particle called the anyon, believed to exist in only two dimensions, can also be created in one dimension. Further studies exploring different types of one-dimensional anyons could bring scientists one step closer to using the particles as a fundamental unit of memory in a quantum computer. A team led by Harvard scientists Joyce Kwan and

Degradation of extreme-ultraviolet optics

Ongoing

The primary degradation process in EUVL tools and satellite instruments begins by the adsorption of water or carbonaceous molecules from the vacuum environment onto the optic surface. The optic is damaged if the molecule undergoes photon-stimulated decomposition before it can (reversibly) thermally

Precision Measurement Grants Program

Ongoing

If funding is available, one new grant in the amount of $50,000 per year will be awarded for the initial period of October 1 through September 30 of the following year. The award may be continued for up to two additional years; however, future or continued funding will be at the discretion of NIST

Extreme ultraviolet optical constants

Ongoing

Measurements of EUV optical constants are often made by measuring the absorption or near-normal-incidence reflectivity, then performing transforms to obtain both the real and imaginary parts of the index. These sorts of measurements have considerable uncertainty because they require knowledge of
