Observation of collectivity enhanced magnetoassociation of 6 Li in the quantum degenerate regime (2022)
Journal Article

The association process of Feshbach molecules is well described by a Landau-Zener transition above the Fermi temperature, such that two-body physics dominates the dynamics. However, using 6 Li atoms and the associated Feshbach resonance at B r = 834.... Read More about Observation of collectivity enhanced magnetoassociation of 6 Li in the quantum degenerate regime.

High-performance, additively-manufactured atomic spectroscopy apparatus for portable quantum technologies (2022)
Journal Article

We demonstrate a miniaturised and highly robust system for performing Doppler-free spectroscopy on thermal atomic vapour for three frequencies as required for cold atom-based quantum technologies. The application of additive manufacturing techniques,... Read More about High-performance, additively-manufactured atomic spectroscopy apparatus for portable quantum technologies.

Performance-Optimized Components for Quantum Technologies via Additive Manufacturing (2021)
Journal Article

Novel quantum technologies and devices place unprecedented demands on the performance of experimental components, while their widespread deployment beyond the laboratory necessitates increased robustness and fast affordable production. We show how th... Read More about Performance-Optimized Components for Quantum Technologies via Additive Manufacturing.

Cold atoms in micromachined waveguides: A new platform for atom-photon interactions (2020)
Journal Article

Hybrid quantum devices, incorporating both atoms and photons, can exploit the benefits of both to enable scalable architectures for quantum computing and quantum communication, as well as chip-scale sensors and single-photon sources. Production of su... Read More about Cold atoms in micromachined waveguides: A new platform for atom-photon interactions.

Prospects for strongly coupled atom-photon quantum nodes (2019)
Journal Article

We discuss the trapping of cold atoms within microscopic voids drilled perpendicularly through the axis of an optical waveguide. The dimensions of the voids considered are between 1 and 40 optical wavelengths. By simulating light transmission across... Read More about Prospects for strongly coupled atom-photon quantum nodes.

Collimated dual species oven source and its characterisation via spatially resolved fluorescence spectroscopy (2018)
Journal Article

We describe the design, construction and characterisation of a collimated, dual-species oven source for generating intense beams of lithium and caesium in UHV environments. Our design produces full beam overlap for the two species. Using an aligned m...

Gravity in the quantum lab (2017)
Journal Article

At the beginning of the previous century, Newtonian mechanics was advanced by two new revolutionary theories, Quantum Mechanics (QM) and General Relativity (GR). Both theories have transformed our view of physical phenomena, with QM accurately predic... Read More about Gravity in the quantum lab.

Quantum decoherence of phonons in Bose–Einstein condensates (2017)
Journal Article

We apply modern techniques from quantum optics and quantum information science to Bose–Einstein condensates(BECs)in order to study, for the first time, the quantum decoherence of phonons of isolated BECs. In the last few years, major advances in the... Read More about Quantum decoherence of phonons in Bose–Einstein condensates.

The UK National Quantum Technologies Hub in sensors and metrology (Keynote Paper) (2016)
Journal Article

The UK National Quantum Technology Hub in Sensors and Metrology is one of four flagship initiatives in the UK National of Quantum Technology Program. As part of a 20-year vision it translates laboratory demonstrations to deployable practical devices,...

Enhanced Raman sideband cooling of caesium atoms in a vapour-loaded magneto-optical trap (2015)
Journal Article

We report enhanced three-dimensional degenerated Raman sideband cooling (3D DRSC) of caesium (Cs) atoms in a standard single-cell vapour-loaded magneto-optical trap. Our improved scheme involves using a separate repumping laser and optimized lattice... Read More about Enhanced Raman sideband cooling of caesium atoms in a vapour-loaded magneto-optical trap.

Versatile cold atom source for multi-species experiments (2014)
Journal Article

We present a dual-species oven and Zeeman slower setup capable of producing slow, high-flux atomic beams for loading magneto-optical traps. Our compact and versatile system is based on electronic switching between different magnetic field profiles an... Read More about Versatile cold atom source for multi-species experiments.

Impurities as a quantum thermometer for a Bose-Einstein condensate (2014)
Journal Article

We introduce a primary thermometer which measures the temperature of a Bose-Einstein Condensate in the sub-nK regime. We show, using quantum Fisher information, that the precision of our technique improves the state-of-the-art in thermometry in the s...
