Physical disassembly of the 4.45 MN (1,000,000 lbf) deadweight machine (DWM) began in FY15 in order to address material galling that developed in key structural

Si-Based Single Spin/Single Photon Measurement, Coherence and Manipulation

Ongoing

We are characterizing Si-based single-electron quantum dots at low temperatures (down to 10 mK) to explore the possibility of quantum coherent manipulation in

Silicon-based single electron current standards

Ongoing

We are working to fabricate and perform low-temperature measurements of CMOS-compatible single electron devices in silicon which could be used as a standard of

Small Mass and Small Force Metrology at NIST

Ongoing

The small mass and force metrology project at NIST leverages the redefinition of the International System of Units (SI) to scale mass and force with electrical

Spinor Condensates and Ultracold Collisions

Ongoing

Interactions between cold atoms can provide us with the means to manipulate matter on the smallest scales. Collisions between laser-cooled atoms, in particular

State-resolved Spectroscopy of Biomolecules

Ongoing

Sensitive and fully state resolved spectroscopic methods in the terahertz (THz) and ultraviolet (UV) regions are being developed to investigate the structure
