Interfacing of an optical nanofiber with tunably spaced atoms in an optical lattice
Hyok Sang Han, Ahreum Lee, Sarthak Subhankar +2
We experimentally demonstrate efficient interfacing of a large number of atoms to an optical nanofiber using an optical lattice with tunable spacing (m) projected onto…

Dual-Frequency Absorption Spectroscopy in Laser-Cooled Rubidium Atoms: Theoretical Modeling and Experiment
Gour Pati, Mauricio Pulido, Fredrik K. Fatemi +2
We demonstrate dual-frequency absorption spectroscopy (DFAS) using laser-cooled 87Rb and 85Rb atoms. Doppler-free resonances with high-contrast are produced, which suggest the suit…

Versatile optical accordion lattices using binary phase transmission gratings
Hyok Sang Han, Ahreum Lee, Sarthak Subhankar +2
Optical accordion lattices are routinely used in quantum simulation and quantum computation experiments to tune optical lattice spacings. Here, we present a technique for creating…
