An alternative representation of multichannel Rydberg spectra: a modified K-matrix and Lu-Fano plot, applied to manganese spectroscopy
Justin D. Piel, Chris H. Greene
The well-known graphical representation called the Lu-Fano plot was originally developed for multi-channel Rydberg spectroscopy, especially in quantum defect theory. The present st…
Quantum science with arrays of metastable helium-3 atoms
Zheyuan Li, Rupsa De, Rishi Sivakumar +7
The motion of atoms in programmable optical tweezer arrays offers many new opportunities for neutral atom quantum science. These include inter- and intra-site atom motion for resou…
Barium Autoionization for Efficient Ion Trap Loading
Zachary J. Wall, Justin D. Piel, Samuel R. Vizvary +7
We report a theoretical and experimental investigation of autoionizing resonances from the manifold in neutral barium for efficient loading of ion traps.…
Broadband femtosecond lasers enable efficient two-photon excitation of the ultranarrow linewidth singlet 1s2s state in helium
Shashank Kumar, Justin D. Piel, Chris H. Greene +1
We propose a broadband, femtosecond two-photon excitation scheme for efficient population transfer to the ultra-narrow linewidth metastable state in helium. Using $12…
