Direct Frequency Comb Laser Cooling and Trapping [PDF]
Physical Review X, 2016 Ultracold atoms, produced by laser cooling and trapping, have led to recent advances in quantum information, quantum chemistry, and quantum sensors. A lack of ultraviolet narrow-band lasers precludes laser cooling of prevalent atoms such as hydrogen ...

Laser Cooling and Trapping of Rare-Earth-Doped Particles
Applied Sciences, 2022 This review focuses on optical refrigeration with the anti-Stokes fluorescence of rare-earth (RE)-doped low-phonon micro- and nanocrystals. Contrary to bulk samples, where the thermal energy is contained in internal vibrational modes (phonons), the ...

Spectroscopic characterization of aluminum monofluoride with relevance to laser cooling and trapping [PDF]
Physical Review A, 2019 Here we report on spectroscopic measurements of the aluminum monofluoride molecule (AlF) that are relevant to laser cooling and trapping experiments. We measure the detailed energy level structure of AlF in the X$^1\Sigma^+$ electronic ground state, in ...

Critical Limitations in Cryogenic Laser Cooling of Solids: Symmetry‐Related Fluorescence Trapping and Condensation‐Induced Parasitic Heating [PDF]
Advanced ScienceLaser cooling of solids to cryogenic temperatures is fundamentally limited by parasitic processes that become critically important below 100 K. While fluoride crystals like Yb3+‐doped LuLiF4 and YLiF4 promise cooling to below 77 K, experimental progress ...

Optical cycling of MgF molecules within the hyperfine states in X(N=1) state [PDF]
Scientific ReportsAchieving laser cooling of molecules necessitates the establishment of a closed optical cycling transition. In contrast to atoms, molecules exhibit additional vibrational and rotational structures, which must be carefully addressed–alongside hyperfine ...

Be+ assisted, simultaneous confinement of more than 15000 antihydrogen atoms [PDF]
Nature CommunicationsAntihydrogen, the bound state of a positron and an antiproton, is the only pure anti-atomic system ever studied. It is produced exclusively in the laboratory, as it has never been observed in nature.
