Intercombination effects in resonant energy transfer (2015)
Journal Article
Vaillant, C., Potvliege, R., & Jones, M. (2015). Intercombination effects in resonant energy transfer. Physical Review A, 92(4), Article 042705. https://doi.org/10.1103/physreva.92.042705

We investigate the effect of intercombination transitions in excitation hopping processes such as those found in Förster resonance energy transfer. Taking strontium Rydberg states as our model system, the breakdown of LS coupling leads to weakly allo... Read More about Intercombination effects in resonant energy transfer.

Spin Squeezing in a Rydberg Lattice Clock (2014)
Journal Article
Gil, L., Mukherjee, R., Bridge, E., Jones, M., & Pohl, T. (2014). Spin Squeezing in a Rydberg Lattice Clock. Physical Review Letters, 112(10), Article 103601. https://doi.org/10.1103/physrevlett.112.103601

We theoretically demonstrate a viable approach to spin squeezing in optical lattice clocks via optical dressing of one clock state to a highly excited Rydberg state, generating switchable atomic interactions. For realistic experimental parameters, th... Read More about Spin Squeezing in a Rydberg Lattice Clock.

Multichannel quantum defect theory of strontium bound Rydberg states (2014)
Journal Article

A quantum state of matter (2013)
Journal Article
Jones, M. (2013). A quantum state of matter

AS THEORETICAL AND experimental physicists probe deeper into the quantum nature of reality, technological advances made in recent years have allowed for a consistent narrowing of the gap between the two approaches. The development and refinement of l... Read More about A quantum state of matter.

Number-resolved imaging of excited-state atoms using a scanning autoionization microscope (2013)
Journal Article
Lochead, G., Boddy, D., Sadler, D., Adams, C., & Jones, M. (2013). Number-resolved imaging of excited-state atoms using a scanning autoionization microscope. Physical Review A, 87(5), Article 053409. https://doi.org/10.1103/physreva.87.053409

We report on a scanning microscopy technique for atom-number-resolved imaging of excited-state atoms. A tightly focused laser beam leads to local autoionization and the resulting ions are counted electronically. Scanning the beam across the cloud bui...

We use a microwave field to control the quantum state of optical photons stored in a cold atomic cloud. The photons are stored in highly excited collective states (Rydberg polaritons) enabling both fast qubit rotations and control of photon-photon in...

Long-range dipole–dipole and quadrupole–quadrupole interactions between pairs of Rydberg atoms are calculated perturbatively for calcium, strontium and ytterbium within the Coulomb approximation. Quantum defects, obtained by fitting existing laser sp... Read More about Long-range Rydberg–Rydberg interactions in calcium, strontium and ytterbium.

We present a study of a cold strontium Rydberg gas. The narrowband laser excitation of Rydberg states in the range n = 20–80 from a 6 mK cloud of strontium atoms is detected using the spontaneous ionization of the Rydberg atoms.
