High performance imaging of Yb atom in shallow clock-magic tweezer by alternating dual-tone narrowline cooling
Yunheung Song, Kangheun Kim, Jeong Ho Han +2
We demonstrate imaging Yb single atoms in clock-magic tweezers of 759.4 nm wavelength, with above 99.9% fidelity and survival. We use alternating dual-tone narrowline imagi…
Low-field Feshbach resonances and three-body losses in a fermionic quantum gas of Dy
Elisa Soave, Vincent Corre, Cornelis Ravensbergen +4
We report on high-resolution Feshbach spectroscopy on a degenerate, spin-polarized Fermi gas of Dy atoms, measuring three-body recombination losses at low magnetic field. F…
Synthetic Hall ladder with tunable magnetic flux
Jeong Ho Han, Dalmin Bae, Yong-il Shin
We describe a synthetic three-leg Hall ladder system with a tunable magnetic flux for neutral Yb atoms in a one-dimensional optical lattice. The ladder legs are formed by t…
Measurement of the dynamic polarizability of Dy atoms near the 626-nm intercombination line
Marian Kreyer, Jeong Ho Han, Cornelis Ravensbergen +4
We report on measurements of the anisotropic dynamical polarizability of Dy near the 626-nm intercombination line, employing modulation spectroscopy in a one-dimensional optical la…
Topological Creutz Ladder in a Resonantly Shaken 1D Optical Lattice
Jin Hyoun Kang, Jeong Ho Han, Yong-il Shin
We report the experimental realization of a topological Creutz ladder for ultracold fermionic atoms in a resonantly driven 1D optical lattice. The two-leg ladder consists of the tw…
Band Gap Closing in a Synthetic Hall Tube of Neutral Fermions
Jeong Ho Han, Jin Hyoun Kang, Yong-il Shin
We report the experimental realization of a synthetic three-leg Hall tube with ultracold fermionic atoms in a one-dimensional optical lattice. The legs of the synthetic tube are co…
Realization of a cross-linked chiral ladder with neutral fermions in an optical lattice by orbital-momentum coupling
Jin Hyoun Kang, Jeong Ho Han, Yong-il Shin
We report the experimental realization of a cross-linked chiral ladder with ultracold fermionic atoms in an optical lattice. In the ladder, the legs are formed by the orbital state…
Photoassociation spectroscopy of ultracold Yb atoms near the intercombination line
Jeong Ho Han, Jin Hyoun Kang, Moosong Lee +1
We report on photoassociation (PA) spectroscopy of a degenerate Fermi gas of Yb atoms near the dissociation limit of the spin-forbidden intercombination t…
Double resonance of Raman transitions in a degenerate Fermi gas
Moosong Lee, Jeong Ho Han, Jin Hyoun Kang +2
We measure momentum-resolved Raman spectra of a spin-polarized degenerate Fermi gas of Yb atoms for a wide range of magnetic fields, where the atoms are irradiated by a pai…
