When NIST scientist Tasshi Dennis first encountered quantum physics as a student, he was skeptical it would ever amount to any practical applications. Little
Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized time keeping, the
This project aims to develop rigorous measurements and methodology needed for determining optical and electrical properties of advanced materials that might be
Much of the activity of the UV Physics Group is aimed at supporting the R&D effort by the microelectronics industry to develop Extreme Ultraviolet Lithography
In the vacuum ultraviolet and extreme ultraviolet (EUV), the indices of refraction of all materials become complex: N = n + ik, or N = 1- d + ik. Here, n is the
In many physical systems, the interaction with an open environment leads to energy dissipation and reduced coherence, making it challenging to control these
