Optical atomic clocks are poised to redefine the SI second, thanks to stability and accuracy more than one hundred times better than the current microwave atomic clock standard. However, the best optical clocks have not seen their performance transfe

A time scale is a procedure for accurately and continuously marking the passage of time. It is exemplified by Coordinated Universal Time (UTC), and provides the backbone for critical navigation tools such as the Global Positioning System (GPS). Prese

Cosmological observations indicate that 85% of all matter in the Universe is dark matter (DM), yet its microscopic composition remains a mystery. One hypothesis is that DM arises from ultralight quantum fields that form macroscopic objects such as to

Analog electrical elements such as mixers, filters, transfer oscillators, isolating buffers, dividers, and even transmission lines contribute technical noise and unwanted environmental coupling in time and frequency measurements. Software defined rad

Single trapped ions are ideal systems in which to test atomic physics at high precision: they are effectively isolated atoms held at rest and largely free from perturbing interactions. This thesis describes several projects developed to study the str

We report progress on 115In+ and 137Ba+ single ion optical frequency standards using all solid-state sources. Both are free from quadrupole field shifts and together enable a search for drift in fundamental constants.

In order to determine the best way to reduce bias and improve relationships among members of different groups, different models of categorization (categorization, de-categorization, re-categorization, and individuation) have been developed and their

Previous research has shown that stereotypes are formed for attributes that have large intergroup differences (Ford & Stangor, 1992) and that there may be an attention shifting mechanism that accounts for learning about the traits of social groups (S

The cross-race effect (CRE) is the tendency for individuals to better recognize same rather than other race faces. White individuals have consistently demonstrated the CRE, showing better recognition for White faces than the faces of minority (e.g.,
