Bringing Atoms to a Standstill: NIST Miniaturizes Laser Cooling

January 21, 2021

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

A New Playbook for Interference

December 17, 2019

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

JQI Researchers Shed New Light on Atomic ‘Wave Function’

May 16, 2019

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

Desktop Cosmology: A Model of the Expanding Universe

April 23, 2018

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

Projects and Programs

Controlling collisions between laser-cooled atoms using magnetic fields and nano-eV colliders

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

Quantum Nonlinear Optics for Metrology and Networking

Quantum nonlinear optics provides a means to generate and manipulate light at the quantum level, with applications in enhanced sensing and metrology, and in

Fundamental Constants in Nature

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 Computation and Simulation with Neutral Atoms

Quantum information processing seeks to use the features of quantum physics to accomplish otherwise intractable computational tasks. The two main thrusts of

Cold-atom-based sensor for measuring pressure in the ultra-high vacuum domain

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

Spinor Condensates and Ultracold Collisions

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

Author(s)

Gordon Drake, Eite Tiesinga

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

Isotope shift spectroscopy of the 1S0 to 3P1 and 1S0 to 3P0 transitions in strontium

November 19, 2020

Author(s)

Gretchen K. Campbell, Hirokazu Miyake, Neal Pisenti, Peter Elgee, Ananya Sitaram

Isotope shift spectroscopy with narrow optical transitions provides a benchmark for atomic struc- ture calculations, and has also been proposed as a way to
