A novel, quantum-based vacuum gauge system invented by researchers at the National Institute of Standards and Technology (NIST) has passed its first test to be
The CODATA Task Group on Fundamental Constants recently produced its 2018 update of a self-consistent set of internationally recommended values of the basic
Four scientists from the National Institute of Standards and Technology (NIST) have reported the latest values for the fundamental constants of nature on June

NIST is building a cold-atom vacuum sensor (CAVS) that will be able to measure pressures in the ultra-high vacuum (UHV) regime corresponding to pressures less
We investigate collisions of atoms in either micro-Kelvin gasses or in nano-colliders, where two small atomic clouds are made to collide with adjustable energy
We are involved in efforts to collate data on precision measurements and the theoretical description of these measurements with the aim to improve the values of
Quantum information processing seeks to use the features of quantum physics to accomplish otherwise intractable computational tasks. The two main thrusts of
Measurement. Science is rooted in measurement: it is from measurements, as unified by theory, that understanding is born. Our comprehension of the universe is
Quantum nonlinear optics provides a means to generate and manipulate light at the quantum level, with applications in enhanced sensing and metrology, and in
Interactions between cold atoms can provide us with the means to manipulate matter on the smallest scales. Collisions between laser-cooled atoms, in particular
We experimentally and theoretically investigate the anisotropic speed of sound of an atomic superfluid (SF) Bose-Einstein condensate in a 1D optical lattice
Ultracold atoms are an ideal platform for understanding system-reservoir dynamics of many-body systems. Here, we study quantum back-action in atomic Bose
Continuously measured interacting quantum systems almost invariably heat, causing loss of quantum coherence. Here we study Bose-Einstein condensates (BECs)

The precise control of dc magnetic fields is crucial in wide range of experimental platforms, from ultracold quantum gases, nuclear magnetic resonance, to
An effect that normally gets in the way of the magnetic trapping of atoms has been harnessed to create a new method for measuring pressure in ultrahigh vacuum
Nothing is truly nothing. A bit paradoxical, sure, but it’s true. Anything that we refer to as “empty,” “devoid,” or “containing nothing” does, in fact, contain
