Craik leads the RAVIOLIS project (SNSF Starting Grant, started July 2025) measuring atomic parity violation in barium ions at <0.1% precision. Her entanglement protocol uses multi-ion entangled states with photonic integrated waveguide addressing to common-mode-reject parity-conserving systematics. Previous work: precision measurement of Ba+ dipole transition probabilities below 1% uncertainty; first laser-guided individual addressing of Ba+ qubits with <10^-4 intensity crosstalk; isotope-shift spectroscopy in Ca+ for fifth-force searches. She is actively recruiting for postdocs and PhD students for the new Ba+ ion trap experiment.

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.
