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

A compact system for ultracold atoms [PDF]
, 2012 This thesis describes the design, construction and optimisation of two compact setups to produce ⁸⁷Rb Bose-Einstein condensates and dual ⁷Li-⁸⁷Rb Magneto-Optical Traps (MOTs). The motivation for compact systems is to have simplified systems to cool the

Grating chips for quantum technologies
Scientific Reports, 2017 We have laser cooled 3 × 106 87Rb atoms to 3 μK in a micro-fabricated grating magneto-optical trap (GMOT), enabling future mass-deployment in highly accurate compact quantum sensors.

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 ...

Alternative techniques for the production and manipulation of ultracold atoms [PDF]
, 2012 This Thesis contains details of the construction and characterisation of a compact apparatus for the cooling of ultracold atoms to quantum degeneracy, and their manipulation in flexible holographic optical traps. We have designed and built two iterations

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 ...

One-dimensional magneto-optical compression of a cold CaF molecular beam
New Journal of Physics, 2017 We demonstrate the one-dimensional, transverse magneto-optical compression of a cold beam of calcium monofluoride (CaF). By continually alternating the magnetic field direction and laser polarizations of the magneto-optical trap (RF MOT), a photon ...

Measurement of vacuum pressure with a magneto-optical trap : a pressure-rise method [PDF]
, 2015 This research was supported by UK EPSRC grant GR/T08272/01, IOP Scotland and the Leverhulme Trust Research Project Grant RPG-2013-074.The lifetime of an atom trap is often limited by the presence of residual background gases in the vacuum chamber.
