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…
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…
Collective Quantum Beats from Distant Multilevel Emitters
Ahreum Lee, Hyok Sang Han, Fredrik K. Fatemi +2
We analyze the dynamics of quantum beats in a system of two V-type three-level atoms coupled to a waveguide. We show that quantum beats can be collectively enhanced or suppressed,…
Observation of vacuum-induced collective quantum beats
Hyok Sang Han, Ahreum Lee, Kanupriya Sinha +2
We demonstrate collectively enhanced vacuum-induced quantum beat dynamics from a three-level V-type atomic system. Exciting a dilute atomic gas of magneto-optically trapped …
Fluorescence detection of single lithium atoms in an optical lattice using Doppler-cooling beams
Hyok Sang Han, Hyun Gyung Lee, Seokchan Yoon +1
We demonstrate in situ fluorescence detection of Li atoms in a 1D optical lattice with single atom precision. Even though illuminated lithium atoms tend to boil out, when the l…
Magic polarization for optical trapping of atoms without Stark-induced dephasing
Huidong Kim, Hyok Sang Han, D. Cho
We demonstrate that the differential ac-Stark shift of a ground-state hyperfine transition in an optical trap can be eliminated by using properly polarized trapping light. We use t…
