Probing nonlocal superconducting fluctuations with covariance noise magnetometry
Gustav Romare, Ilya Esterlis, Shimon Kolkowitz +1
The nonlocal superconducting fluctuation corrections to the conductivity tensor are calculated within the time-dependent Ginzburg-Landau framework, and the…
Gravitational-wave astronomy with a space-based optical clock network
Dhruva Ganapathy, Divya Singh, Sammith Singamsetty +1
Since the first detection of a merging binary black hole system a decade ago, gravitational-wave astronomy has emerged as a powerful tool for astrophysics. Future space-based obser…
Laser cooling and qubit measurements on a forbidden transition in neutral Cs atoms
J. Scott, H. M. Lim, U. Singla +6
We experimentally demonstrate background-free, hyperfine-level-selective measurements of individual Cs atoms by simultaneous cooling to and imaging on the $6s_{1/2}\r…
Towards a temperature-insensitive composite diamond clock
Sean Lourette, Andrey Jarmola, Jabir Chathanathil +8
Frequency references based on solid state spins promise simplicity, compactness, robustness, multifunctionality, ease of integration, and high densities of emitters. Nitrogen-vacan…
Enhancing optical lattice clock coherence times with erasure conversion
Shuo Ma, Jonathan Dolde, Xin Zheng +6
Increasing coherent interrogation times is central to advancing the precision of optical clocks. Synchronous differential optical clock comparisons have now demonstrated atomic coh…
Direct measurement of the 3P0 clock state natural lifetime in 87Sr
Jonathan Dolde, Dhruva Ganapathy, Xin Zheng +3
Optical lattice clocks based on the narrow (5s2)1S0 - (5s5p)3P0 transition in neutral strontium (Sr) are among the most precise and accurate measurement devices in existence. Altho…
