Laser-cooled polyatomic molecules for improved electron electric dipole moment searches

New Journal of Physics, 2020
Doppler and Sisyphus cooling of ^174 YbOH are achieved and studied. This polyatomic molecule has high sensitivity to physics beyond the Standard Model and represents a new class of species for future high-precision probes of new T-violating physics.

Resonance Raman optical cycling for high-fidelity fluorescence detection of molecules

Physical Review Research, 2021
We propose and demonstrate a technique that combines Raman scattering and optical cycling in molecules with diagonal Franck-Condon factors. This resonance Raman optical cycling manipulates molecules to behave like efficient fluorophores, with discrete ...

Determination of CaOH and CaOCH3 vibrational branching ratios for direct laser cooling and trapping

New Journal of Physics, 2019
Alkaline earth monoalkoxide free radicals (MORs) have molecular properties conducive to direct laser cooling to sub-millikelvin temperatures. Using dispersed laser induced fluorescence measurements from a pulsed supersonic molecular beam source we ...

Laser Cooling of Lanthanides: from Optical Clocks to Quantum Simulators

EPJ Web of Conferences, 2015
We discuss current progress in laser cooling of lanthanides (Er, Yb, Dy, Tm etc.) focusing on applications. We describe some important peculiarities taking Thulium atom as an example: Two stage laser cooling, trapping in an optical lattice, anisotropic ...

Laser Cooling of two trapped ions: Sideband cooling beyond the Lamb-Dicke limit [PDF]

, 1998
We study laser cooling of two ions that are trapped in a harmonic potential and interact by Coulomb repulsion. Sideband cooling in the Lamb-Dicke regime is shown to work analogously to sideband cooling of a single ion.
