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…

A practical guide to feedback control for Pound-Drever-Hall laser linewidth narrowing
Wance Wang, Sarthak Subhankar, Joseph W. Britton
The Pound-Drever-Hall (PDH) technique for laser linewidth narrowing is widely used by AMO experimentalists. However, achieving a high-performance PDH locking requires substantial e…

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…
