Duellmann heads nuclear chemistry at JGU (TRIGA reactor site) with joint appointments at GSI and the Helmholtz Institute Mainz, working on the production, chemical separation and characterization of the heaviest elements. For this search the relevant thread is 229Th: his group supplies and prepares the isomeric thorium samples and molecular thorium ions that Wendt's laser spectroscopy and Schmidt-Kaler's ion traps interrogate en route to a nuclear clock, and he is part of the broader radioactive-molecule programme aimed at symmetry-violation searches. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), the pivot is toward the next frontier of frequency metrology, where the 'sensor' is a nucleus rather than an electron shell -- an unusually good chemistry/physics interface for a postdoc.

The Endres group assembles programmable arrays of individually trapped neutral atoms (Rydberg and alkaline-earth) to advance quantum metrology, entanglement-enhanced optical clocks, and many-body simulation, demonstrating record atom-array optical-clock stability and quantum-enhanced sensing protocols. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/√Hz sensitivity.

Flambaum is one of the most cited atomic theorists alive and the intellectual source of a large fraction of the modern precision-AMO new-physics programme. His group computes the atomic and molecular structure factors that convert an experimental frequency shift into a bound on new physics: enhancement factors for electron and nuclear EDMs, atomic parity violation, the sensitivity of clock transitions to variation of the fine-structure constant, and — most relevant to quantum sensing — the response of atomic clocks, magnetometers and comagnetometers to ultralight/axion-like dark matter fields. He proposed much of the theory behind using networks of quantum sensors as dark matter detectors. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — his theory is what tells an experimentalist what a pT/sqrt(Hz) magnetometer or a 10^-18 clock actually constrains: without it, a spin-precession measurement is just a number. Theory group; a sensing postdoc would collaborate rather than join.

Foot leads the Ultracold Quantum Matter group and is one of the two Oxford physics PIs co-leading the AION project at Oxford. His group develops laser-cooled strontium atom sources with the ultranarrow Sr-87 clock transition for large-scale single-photon atom interferometry. Near-term goals include the AION-10, a 10-m baseline vertical atom interferometer currently under construction in the Beecroft Building stairwell, targeting dark matter searches and mid-band gravitational wave detection. Foot's group also studies non-equilibrium 2D quantum gas physics (BKT transition, vortex dynamics) using matter-wave interferometry. AION is linked to MAGIS-100 at Fermilab.

The Geraci group employs high-Q resonant sensors for ultra-sensitive force and field detection in searches for new physics beyond the Standard Model. Key thrusts: (1) Optically-trapped levitated dielectric nanospheres and microspheres achieving zeptonewton (10⁻²¹ N) force sensitivity, applied to probing short-range deviations from Newtonian gravity at micrometer scales; (2) ARIADNE, an international NMR-based experiment using superfluid ³He to search for the QCD axion via axion-mediated spin-dependent forces between a rotating mass and polarized nuclei; (3) Collaboration on MAGIS-100, the 100 m-tall atom interferometer at Fermilab for gravitational wave detection in the mid-band (0.3–10 Hz) and ultralight dark matter searches; (4) Cryogenic optical cavity dark matter comparisons with Gabrielse and Kovachy groups.

Goldfarb studies coherent effects in atomic vapours - EIT and slow light, spin-noise spectroscopy of spin-environment interaction, and EIT-based Rydberg-atom radio-frequency field sensing (electrometry) in warm cells. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work adds atomic-vapour electrometry and coherence spectroscopy.
