Modulation Transfer Spectroscopy of the D1 Transition of Potassium: Theory and Experiment
Andrew D. Innes, Prosenjit Majumder, Heung-Ryoul Noh +1
We report on a study of modulation transfer spectroscopy of the () transition of naturally abundant potassium in a room-temp…
Double-EIT Ground-State Cooling of Stationary Two-Dimensional Ion Lattices
Mu Qiao, Ye Wang, Zhengyang Cai +6
We theoretically and experimentally investigate double electromagnetically induced transparency (double-EIT) cooling of two-dimensional ion crystals confined in a Paul trap. The do…
Nonlinear, Nonequilibrium and Collective Dynamics in a Periodically Modulated Cold Atom System
Geol Moon, Myoung-Sun Heo, Yonghee Kim +2
The physics of critical phenomena in a many-body system far from thermal equilibrium is an interesting and important issue to be addressed both experimentally and theoretically. Th…
Optical pumping effect in absorption imaging of F=1 atomic gases
Sooshin Kim, Sang Won Seo, Heung-Ryoul Noh +1
We report our study of the optical pumping effect in absorption imaging of Na atoms in the hyperfine spin states. Solving a set of rate equations for the spin populati…
Three-photon coherence in a ladder-type atomic system
Heung-Ryoul Noh, Han Seb Moon
We present a theoretical study of three-photon electromagnetically induced absorption for a ladder-type three-level atomic system. A probe beam was tuned to the lower line and two…
An Ideal Mean-Field Transition in a Modulated Cold Atom System
Myoung-Sun Heo, Yonghee Kim, Kihwan Kim +5
We show that an atomic system in a periodically modulated optical trap displays an ideal mean-field symmetry-breaking transition. The symmetry is broken with respect to time transl…
