It’s cool to be small. Scientists at the National Institute of Standards and Technology (NIST) have miniaturized the optical components required to cool atoms
Particles can sometimes act like waves, and photons (particles of light) are no exception. Just as waves create an interference pattern, like ripples on a pond
Physicists have demonstrated a new way to obtain the essential details that describe an isolated quantum system, such as a gas of atoms, through direct
When the universe was very young – about a trillionth of a trillionth of a trillionth of a second after the Big Bang – it underwent a sudden explosive expansion

Quantum nonlinear optics provides a means to generate and manipulate light at the quantum level, with applications in enhanced sensing and metrology, and in
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
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
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 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
Weak measurement in tandem with real-time feedback control is a new route toward engineering novel non-equilibrium quantum matter. Here we develop a theoretical
Within the Hartree atomic unit systems, the Schrödinger equation becomes parameter free. But there's more to it than making a student's life easier, as Gordon

We demonstrate a compact magneto-optical trap (MOT) of alkaline-earth atoms using a nanofabricated diffraction grating chip. A single input laser beam, resonant
For his pioneering work and leadership in developing quantum simulation techniques to investigate natural phenomena too complex for traditional mathematical computation.
