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.

Christoph Westbrook co-heads the Quantum Gases group at LCF/IOGS. Research: (1) metastable helium (He*) BEC and ultracold atomic gases — 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.

Witte's group builds table-top extreme-ultraviolet sources via high-harmonic generation and combines them with coherent diffractive imaging (ptychography) to visualize 3D nanostructures, such as multilayer IC features, at resolutions well below the diffraction limit of visible light. The lab also works on lensless microscopy, photoacoustic imaging/metrology, and ultrafast electron/HHG dynamics, sitting at the interface of fundamental attosecond-adjacent light-matter physics and applied nanometrology; the group is actively hiring as it ramps up at TU Delft.

Tarik Yefsah's group at LKB studies strongly interacting ultracold Fermi gases. Research: (1) Fermi gas mixtures — 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.

Yzombard works on laser-cooling techniques for exotic ions and antimatter precursors as part of the GBAR (Gravitational Behaviour of Antihydrogen at Rest) collaboration, aiming to measure the free-fall acceleration of antihydrogen as a fundamental test of the equivalence principle.
