Narrow-line magneto-optical trap for erbium
, 2012 We report on the experimental realization of a robust and efficient magneto-optical trap for erbium atoms, based on a narrow cooling transition at 583nm. We observe up to $N=2 \times 10^{8}$ atoms at a temperature of about $T=15 \mu K$.

Magneto-optical trapping forces for atoms and molecules with complex level structures
New Journal of Physics, 2015 Laser cooling and magneto-optical trapping of molecules typically involves multiple transitions driven by several laser frequencies. We analyze how magneto-optical trapping forces depend on the angular momenta, F _l and F _u , and the g -factors, g _l ...

An Asymmetric Magneto-Optical Trap
, 2010 In this article we have presented experimental and theoretical works on the asymmetric magneto-optical trap. In Sec. 2, we have studied parametric resonance in a magneto-optical trap. We have described a theoretical aspect of parametric resonance by the analytic and numerical methods.

All-Optical Production of Chromium Bose-Einstein Condensates
, 2008 We report on the production of ^52Cr Bose Einstein Condensates (BEC) with an all-optical method. We first load 5.10^6 metastable chromium atoms in a 1D far-off-resonance optical trap (FORT) from a Magneto Optical Trap (MOT), by combining the use of Radio

Compact ultracold electron source based on a grating magneto-optical trap
Physical Review Accelerators and Beams, 2019 The ultrafast and ultracold electron source, based on near-threshold photoionization of a laser-cooled and trapped atomic gas, offers a unique combination of low transverse beam emittance and high bunch charge. Its use is however still limited because of

, 2014 We study the center-of-mass motion in systems of trapped interacting particles with space- and velocity-dependent friction and anharmonic traps. Our approach, based on a dynamical ansatz assuming a fixed density profile, allows us to obtain information ...

Vibrational branching ratios and hyperfine structure of BH and its suitability for laser cooling
Frontiers in Physics, 2014 The simple structure of the BH molecule makes it an excellent candidate for direct laser cooling. We measure the branching ratios for the decay of the A^{1}Pi (v'=0) state to vibrational levels of the ground state, X^{1}Sigma^{+}, and find that they are ...

Sub-Doppler Cooling, State Preparation, and Optical Trapping of a Triel Atom
PRX QuantumUltracold gases of atoms from main group III (group 13) of the periodic table, also known as “triel elements,” have great potential for a new generation of quantum matter experiments.

Manufacturing a thin wire electrostatic trap (TWIST) for ultracold polar molecules
, 2007 We present a detailed description on how to build a Thin WIre electroStatic Trap (TWIST) for ultracold polar molecules. It is the first design of an electrostatic trap that can be superimposed directly onto a magneto optical trap (MOT).
