Direct comparison of two spin squeezed optical clocks below the quantum projection noise limit
John M Robinson, Maya Miklos, Yee Ming Tso +5
Building scalable quantum systems that demonstrate genuine performance enhancement based on entanglement is a major scientific goal for fields including computing, networking, simu…
Hamiltonian engineering of spin-orbit coupled fermions in a Wannier-Stark optical lattice clock
Alexander Aeppli, Anjun Chu, Tobias Bothwell +5
Engineering a Hamiltonian system with tunable interactions provides opportunities to optimize performance for quantum sensing and explore emerging phenomena of many-body systems. A…
Preparation of the spin-Mott state: a spinful Mott insulator of repulsively bound pairs
Julius de Hond, Jinggang Xiang, Woo Chang Chung +5
We observe and study a special ground state of bosons with two spin states in an optical lattice: the spin-Mott insulator, a state that consists of repulsively bound pairs which is…
Resolving the gravitational redshift within a millimeter atomic sample
Tobias Bothwell, Colin J. Kennedy, Alexander Aeppli +5
Einstein's theory of general relativity states that clocks at different gravitational potentials tick at different rates - an effect known as the gravitational redshift. As fundame…
Optical Atomic Clock Comparison through Turbulent Air
Martha I. Bodine, Jean-Daniel Deschênes, Isaac H. Khader +32
We use frequency comb-based optical two-way time-frequency transfer (O-TWTFT) to measure the optical frequency ratio of state-of-the-art ytterbium and strontium optical atomic cloc…
Frequency Ratio Measurements with 18-digit Accuracy Using a Network of Optical Clocks
Boulder Atomic Clock Optical Network, Collaboration, : +35
Atomic clocks occupy a unique position in measurement science, exhibiting higher accuracy than any other measurement standard and underpinning six out of seven base units in the SI…
Demonstration of a time scale based on a stable optical carrier
William R. Milner, John M. Robinson, Colin J. Kennedy +13
We demonstrate a time scale based on a phase stable optical carrier that accumulates an estimated time error of ps over 34 days of operation. This all-optical time scale…
JILA SrI Optical Lattice Clock with Uncertainty of
Tobias Bothwell, Dhruv Kedar, Eric Oelker +5
We report on an improved systematic evaluation of the JILA SrI optical lattice clock, achieving a nearly identical systematic uncertainty compared to the previous strontium accurac…
Optical clock intercomparison with precision in one hour
E. Oelker, R. B. Hutson, C. J. Kennedy +14
Improvements in atom-light coherence are foundational to progress in quantum information science, quantum optics, and precision metrology. Optical atomic clocks require local oscil…
Coherence Times of Bose-Einstein Condensates beyond the Shot-Noise Limit via Superfluid Shielding
William Cody Burton, Colin J. Kennedy, Woo Chang Chung +3
We demonstrate a new way to extend the coherence time of separated Bose-Einstein condensates that involves immersion into a superfluid bath. When both the system and the bath have…
Observation of Bose-Einstein Condensation in a Strong Synthetic Magnetic Field
Colin J. Kennedy, William Cody Burton, Woo Chang Chung +1
Extensions of Berry's phase and the quantum Hall effect have led to the discovery of new states of matter with topological properties. Traditionally, this has been achieved using g…
Weyl points in three-dimensional optical lattices: synthetic magnetic monopoles in momentum space
Tena Dubček, Colin J. Kennedy, Ling Lu +3
We show that Hamiltonians with Weyl points can be realized for ultracold atoms using laser-assisted tunneling in three-dimensional optical lattices. Weyl points are synthetic magne…
Spin-orbit coupling and spin Hall effect for neutral atoms without spin-flips
Colin J. Kennedy, Georgios A. Siviloglou, Hirokazu Miyake +2
We propose a scheme which realizes spin-orbit coupling and the spin Hall effect for neutral atoms in optical lattices without relying on near resonant laser light to couple differe…
Realizing the Harper Hamiltonian with Laser-Assisted Tunneling in Optical Lattices
Hirokazu Miyake, Georgios A. Siviloglou, Colin J. Kennedy +2
We experimentally implement the Harper Hamiltonian for neutral particles in optical lattices using laser-assisted tunneling and a potential energy gradient provided by gravity or m…
