A two species trap for chromium and rubidium atoms [PDF]
, 2004 We realize a combined trap for bosonic chromium 52Cr and rubidium 87Rb atoms. First experiments focus on exploring a suitable loading scheme for the combined trap and on studies of new trap loss mechanisms originating from simultaneous trapping of two ...

Maximizing the capture velocity of molecular magneto-optical traps with Bayesian optimization
New Journal of Physics, 2021 Magneto-optical trapping (MOT) is a key technique on the route towards ultracold molecular ensembles. However, the realization and optimization of magneto-optical traps with their wide parameter space is particularly difficult.

Nonequilibrium Steady State in a Large Magneto-Optical Trap
Atoms, 2022 Considering light-mediated long-range interactions between cold atoms in a magneto-optical trap (MOT), we present numerical evidence of a nonequilibrium steady state (NESS) for sufficiently large number of atoms (>108). This state manifests itself as the

Single atoms in a standing-wave dipole trap [PDF]
, 2002 We trap a single cesium atom in a standing-wave optical dipole trap. Special experimental procedures, designed to work with single atoms, are used to measure the oscillation frequency and the atomic energy distribution in the dipole trap.

A compact high-flux cold atom beam source [PDF]
, 2011 We report on an efficient and compact high-flux Cs atom beam source based on a retro-reflected two-dimensional magneto-optical trap (2D MOT). We realize an effective pushing field component by tilting the 2D MOT collimators towards a separate three ...

Trapping radioactive ^{82}Rb in an optical dipole trap and evidence of spontaneous spin polarization [PDF]
, 2007 Optical trapping of selected species of radioactive atoms has great potential in precision measurements for testing fundamental physics such as EDM, PNC and parity violating beta-decay asymmetry correlation coefficients.

Time-domain optics for atomic quantum matter
New Journal of Physics, 2021 We investigate time-domain optics for atomic quantum matter. Within a matter-wave analog of the thin-lens formalism, we study optical lenses of different shapes and refractive powers to precisely control the dispersion of Bose–Einstein condensates ...

Creating long-lived neutral-atom traps in a cryogenic environment [PDF]
, 1995 We describe techniques for creating long-lived magneto-optical and magnetostatic traps for neutral atoms. These traps exist in a sealed cryogenic environment with a temperature near 4 K, where the background gas pressure can be extremely low.

Integrating planar photonics for multi-beam generation and atomic clock packaging on chip
Light: Science & Applications, 2023 The commercialization of atomic technologies requires replacing laboratory-scale laser setups with compact and manufacturable optical platforms. Complex arrangements of free-space beams can be generated on chip through a combination of integrated ...

Laser slowing of CaF molecules to near the capture velocity of a molecular MOT [PDF]
, 2016 Laser slowing of CaF molecules down to the capture velocity of a magneto-optical trap (MOT) for molecules is achieved. Starting from a two-stage buffer gas beam source, we apply frequency-broadened "white-light" slowing and observe approximately 6x10^4 ...
