The distant galaxies GN-z11 (z ≈ 10.957) and CAPERS-LRD-z9 (z ≈ 9), recently observed with the James Webb Space Telescope (JWST), challenge conventional cosmology with their compact sizes, remarkably compact morphologies, intense starburst activities, and over massive central supermassive black holes (SMBHs) …

The weakness of the force of gravity compared to the electromagnetic force and other fundamental forces is referred to as the hierarchy problem. If gravity propagates in several additional spatial dimensions that are large compared with the Planck scale, the hypothesis is …

Vector Atomic has developed optical clocks using iodine vapor cells. These clocks provide excellent short-term instability, require neither laser cooling nor cavity pre-stabilization, are insensitive to motion, and maintain holdovers of <1ns for several days.

We explore photonic-integrated circuits and metasurface optics to generate multiple, large diameter, circularly polarized laser beams for a compact strontium optical clock. We demonstrate an 88Sr magneto-optical trap with integrated photonics in a liter-scale apparatus.

We demonstrate visible integrated photonics, using an inverse-design approach. Tantalum-pentoxide nanophotonics offers <2 dB/cm waveguide loss across 450-2000 nm range. We create a suite of passives, including arbitrary-polarization grating sources for a Sr optical clock.
