Hutzler's group uses cold and ultracold polar molecules (including polyatomics and laser-cooled species) as exquisitely sensitive probes of fundamental symmetry violation, searching for the electron electric dipole moment and other signatures of physics beyond the Standard Model; the group is developing molecules with enhanced sensitivity and internal co-magnetometry. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/√Hz sensitivity.
Iivanainen develops OPM-MEG instrumentation and analysis - sensor arrays, on-scalp sampling, and source modelling (previously at Aalto). The work complements NV-center diamond ensemble quantum sensing (DEER, NMR, T1 relaxometry) at pT/sqrt(Hz) sensitivity by pursuing the same field-sensing goals in a different physical platform.
Ilmoniemi is a founder of modern MEG and TMS-EEG; he develops MEG/OPM-MEG methods, minimum-norm source estimation and multi-locus TMS neurotechnology. The work complements NV-center diamond ensemble quantum sensing (DEER, NMR, T1 relaxometry) at pT/sqrt(Hz) sensitivity by pursuing the same field-sensing goals in a different physical platform.
Imamoglu leads the Quantum Photonics Group at ETH, working at the intersection of quantum optics and condensed matter physics. Research directions: (1) Quantum emitters in 2D semiconductors — TMD monolayers (MoSe2, WSe2) host localized excitons that act as single-photon emitters; electrically tunable quantum dots in TMD heterostructures with high purity and spin-photon entanglement; developing them as quantum sensors of local electronic correlations at nanometer scales; (2) Strongly correlated electron physics — Mott insulator / Wigner crystal phases in moiré TMD bilayers probed optically with single-photon resolution; mapping electronic phases with nanometer spatial resolution; (3) Polariton quantum fluids — exciton-polaritons in 2D semiconductor microcavities; (4) Quantum nonlinear optics — photon-photon interactions via giant Kerr nonlinearities in strongly coupled quantum dots. Quantum sensing angle: quantum emitters as nanoscale probes of correlated phases.
Indelicato performs high-precision X-ray spectroscopy of highly-charged and exotic (muonic, antiprotonic, pionic) atoms at large-scale facilities to test bound-state quantum electrodynamics in the strong-field regime, complementing LKB's hydrogen/molecular-ion precision-spectroscopy programmes.
Irwin invented the transition-edge sensor (TES) and pioneered SQUID-multiplexed readout now used throughout CMB and dark-matter detector arrays; his group builds quantum-limited electromagnetic sensors for axion dark matter searches (DMRadio) and cryogenic calorimeters, pushing sensitivity to the standard quantum limit and beyond -- a field of quantum sensing that, like ensemble NV-diamond magnetometry reaching pT/√Hz sensitivities, trades off bandwidth and volume for extreme field sensitivity.
Jackson Kimball uses atomic magnetometry (including SERF and nonlinear magneto-optical rotation) for tests of fundamental symmetries and ultralight dark-matter searches; he co-leads GNOME and contributes SERF magnetometry to CASPEr. This vapour-phase approach reaches femto-to-picotesla sensitivities complementary to NV-center diamond ensemble quantum sensors (DEER, nano-NMR, T1 relaxometry) that operate near the pT/sqrt(Hz) regime.
Develops scalable, atomically-precise low-dimensional (2D/1D/0D) materials and heterostructures, focusing on single-photon emitters and spin defects in semiconductors for quantum sensing and molecular-based qubits.
Prof. Jacobsen's group develops novel methods, instruments, and analysis approaches for X-ray nanoscale imaging and applies them to biology and environmental science, using the Advanced Photon Source (APS) at Argonne. Directions: (1) Scanning X-ray fluorescence microscopy (SXFM) for organ-wide and nanoscale elemental mapping of metals (zinc, copper, iron) in biological tissues — central to the NIH-funded QE-Map national resource; imaging how metals regulate cellular functions, synaptic zinc signaling, and neurodegenerative disease; (2) X-ray ptychography and coherent diffractive imaging (CDI) for nanoscale biological imaging beyond the diffraction limit with improved dose efficiency; (3) Development of new algorithms, optics (zone plates), and detector systems to push spatial resolution and dose efficiency in X-ray microscopy — including lensless imaging methods and compressed-sensing reconstruction. Joint appointment at Argonne National Laboratory (Argonne Distinguished Fellow); also involved in QE-Map resource with Kozorovitskiy and Hao Zhang (McCormick).
Jacqmin works on chip-trapped ultracold-atom sources and matter-wave interferometry within LKB's Atom Chips team, part of the broader effort (alongside fiber Fabry-Perot microcavity work) to build compact, chip-scale atomic sensors and clocks.
