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

Nonlinear localized modes in one-dimensional nanoscale dark-state optical lattices
Nanophotonics, 2022 Optical lattices (OLs) with conventional spatial periodic λ/2, formed by interfering the counterpropagating laser beams with wavelength λ, are versatile tools to study the dynamical and static properties of ultracold atoms. OLs with subwavelength spatial

A scalable quantum computing platform using symmetric-top molecules
New Journal of Physics, 2019 We propose a new scalable platform for quantum computing (QC)—an array of optically trapped symmetric-top molecules (STMs) of the alkaline earth monomethoxide (MOCH _3 ) family.

Microwave quantum logic spectroscopy and control of molecular ions
New Journal of Physics, 2013 A general method for rotational microwave spectroscopy and control of polar molecular ions via direct microwave addressing is considered. Our method makes use of spatially varying ac Stark shifts, induced by far off-resonant, focused laser beams to ...

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 ...

Ultracold atoms in dressed potentials [PDF]
, 2018 Time-varying fields are widely used to extend the accessible range of trapping potentials for ultracold atoms. This work explores two very different examples of such fields, in the radiofrequency and optical regimes, whose interactions with trapped atoms

Impact of non-unitary spin squeezing on atomic clock performance
New Journal of Physics, 2018 Spin squeezing is a form of entanglement that can improve the stability of quantum sensors operating with multiple particles, by inducing inter-particle correlations that redistribute the quantum projection noise.

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 ...
