A passively pumped vacuum package sustaining cold atoms for more than 200 days
Bethany J. Little, Gregory W. Hoth, Justin Christensen +5
Compact cold-atom sensors depend on vacuum technology. One of the major limitations to miniaturizing these sensors are the active pumps -- typically ion pumps -- required to sustai…

Cold-atom clock based on a diffractive optic
Rachel Elvin, Gregory W. Hoth, Michael Wright +5
Clocks based on cold atoms offer unbeatable accuracy and long-term stability, but their use in portable quantum technologies is hampered by a large physical footprint. Here, we use…

Multi-axis atom interferometer gyroscope with a single source of atoms
Yun-Jhih Chen, Azure Hansen, Gregory W. Hoth +4
Using the technique of point source atom interferometry, we characterize the sensitivity of a multi-axis gyroscope based on free-space Raman interrogation of a single source of col…
