Technique - (34) Ultracold atom trapping (BEC/MOT)

Type: Experimental

Description: Laser cooling, magneto-optical trapping, and evaporative cooling to quantum degeneracy.

Department(s)/lab(s): Physics / QET Labs | GECKO Group (Weidner Lab) @ Bristol
Summary:

Carrie Weidner's GECKO group develops experimental quantum sensing and simulation with cold atoms and hot atomic vapours. Key directions: (1) robust atom interferometry for 6-axis inertial sensing using optical lattice potentials (EPSRC-funded, Infleqtion partnership); (2) magnetic field imaging with squeezed light in hot atom vapour cells (wide-field OPM-type sensing using Faraday rotation); (3) quantum optimal control theory for atom interferometric sensors. The group is establishing a full ultracold atom apparatus for quantum simulation and sensing. Active postdoc positions.

Department(s)/lab(s): Physics / Laboratoire Charles Fabry (IOGS/X) | Quantum Gases Group LCF (Westbrook/Aspect Lab) @ X
Summary:

Christoph Westbrook co-heads the Quantum Gases group at LCF/IOGS. Research: (1) metastable helium (He*) BEC and ultracold atomic gases β€” atom optics, Bose-Hubbard physics, Anderson localization; (2) correlated atom pair production via four-wave mixing for quantum atom optics sensing; (3) atom laser and matter-wave interferometry. The group pioneered the He* BEC and uses correlated atom pairs for quantum sensing analogous to two-photon quantum optics.

Department(s)/lab(s): Physics | Yan Lab @ UChicago
Summary:

Yan built the first quantum gas microscope for ultracold molecules and uses programmable tweezer arrays of fermionic atoms and dipolar molecules to realize custom quantum many-body Hamiltonians (Hubbard and spin models) with single-site resolution. This is primarily a quantum-simulation platform rather than a sensing one, so it is kept as an unpreferred/borderline entry; the same site-resolved tweezer/microscope toolkit underlies emerging proposals for distributed tweezer-array quantum sensors, which is the basis for inclusion.

Department(s)/lab(s): Physics / LKB | Ultracold Fermi Gases Group (Yefsah/LKB) @ ENS Paris
Summary:

Tarik Yefsah's group at LKB studies strongly interacting ultracold Fermi gases. Research: (1) Fermi gas mixtures β€” quantum simulation of condensed matter phenomena (BCS-BEC crossover, Fermi polaron); (2) quantum gas microscope experiments imaging individual atoms in optical lattices; (3) novel quantum phases in Fermi-Hubbard systems ('fermionic waltz' publication 2026). Relevant to quantum simulation and quantum gas-based sensing.
