Feasibility of an optical fiber clock
We explore the feasibility of a fiber clock, i.e., a compact, high-precision, optical lattice atomic clock based on atoms trapped inside a hollow-core optical fiber. Such a setup offers an intriguing potential both for a ...
Coherence Preservation of a Single Neutral Atom Qubit Transferred between Magic-Intensity Optical Traps
We demonstrate that the coherence of a single mobile atomic qubit can be well preserved during a transfer process among different optical dipole traps (ODTs). This is a prerequisite step in realizing a large-scale neutral ...
Efficient repumping of a Ca magneto-optical trap
We investigate the limiting factors in the standard implementation of the Ca magneto-optical trap. We find that intercombination transitions from the 4s5p(1)P(1) state used to repump the electronic population from the 3d4s ...
Hyperfine-induced quadrupole moments of alkali-metal-atom ground states and their implications for atomic clocks
Spherically symmetric ground states of alkali-metal atoms do not posses electric quadrupole moments. However, the hyperfine interaction between nuclear moments and atomic electrons distorts the spherical symmetry of ...
Atomic clocks and dark-matter signatures
Recent developments in searches for dark-matter candidates with atomic clocks are reviewed. The intended audience is the atomic clock community.
Sensitivity of Atom Interferometry to Ultralight Scalar Field Dark Matter
We discuss the use of atom interferometry as a tool to search for dark matter (DM) composed of virialized ultralight fields (VULFs). Previous work on VULF DM detection using accelerometers has considered the possibility ...
Search for domain wall dark matter with atomic clocks on board global positioning system satellites
Cosmological observations indicate that dark matter makes up 85% of all matter in the universe yet its microscopic composition remains a mystery. Dark matter could arise from ultralight quantum fields that form macroscopic ...
Quantum Network of Atom Clocks: A Possible Implementation with Neutral Atoms
We propose a protocol for creating a fully entangled Greenberger-Horne-Zeilinger-type state of neutral atoms in spatially separated optical atomic clocks. In our scheme, local operations make use of the strong dipole-dipole ...
Effects of molecular resonances on Rydberg blockade
We study the effect of resonances associated with complex molecular interaction of Rydberg atoms on Rydberg blockade. We show that densely spaced molecular potentials between doubly excited atomic pairs become unavoidably ...
