Buchmueller is the lead PI of the AION consortium (~£10M funded by UKRI/STFC), leading Imperial's ultracold strontium lab developing single-photon large-momentum-transfer atom interferometry on the Sr clock transition. Key achievements: prototype Sr differential atom interferometer operating at the Standard Quantum Limit with laser noise rejection demonstrated (arXiv 2504.09158, Apr 2025); AION-10 technical design report published (Aug 2025). Buchmueller also leads the AEDGE space mission concept for the European Space Agency, seeking to deploy a km-scale Sr atom interferometer in space for dark matter and mid-frequency gravitational wave detection. Deeply involved in MAGIS-100 partnership (Fermilab) and Cold Atoms in Space community building with 130+ proponents. Active in CMS Collaboration at CERN.
Clade works on atom-recoil interferometry, using Bloch-oscillation-enhanced light-pulse atom interferometers to measure the photon recoil velocity of atoms with extreme precision, from which the fine-structure constant is extracted as one of the most stringent tests of QED and the Standard Model. This precision-metrology approach is a core exemplar of atom-interferometric quantum sensing at LKB.
Cotter leads the Quantum Navigation research stream at Imperial's Centre for Cold Matter. He develops compact, fieldable cold-atom inertial sensors for GPS-denied navigation. Milestones: first demonstration of a cold-atom accelerometer on the London Underground (measuring acceleration/vibration in a real transit environment); successful field trials of quantum inertial sensors aboard the Royal Navy research ship XV Patrick Blackett (2023); Arctic field trials with Royal Navy (2025). His sensors use magnetically launched cold-atom Rb clouds and simultaneous multi-axis interferometry. He also contributes to AION-related atom interferometry work and the Quantum Technology Hub in Sensors and Timing. Department of Materials cross-appointment.
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.
Graham is a theoretical physicist whose phenomenological proposals directly motivate several leading quantum-sensing experiments -- co-designing the MAGIS atom-interferometer program for gravitational waves and ultralight dark matter, and the DMRadio lumped-element axion search -- bridging fundamental theory with concrete experimental sensor concepts rather than running his own lab. [Included as a borderline/theory-side match per filter guidance; kept for review.]
Gratta's group works at the interface of atomic and particle physics, developing cold-atom interferometric gravimeters and gradiometers for tests of gravity alongside searches for neutrinoless double-beta decay using liquid-xenon TPCs (EXO-200/nEXO), spanning quantum sensing hardware and rare-event particle detection.
Guellati-Khelifa leads LKB's atom-interferometric determination of the fine-structure constant via precision measurement of the atomic recoil velocity using Bloch oscillations in an optical lattice, one of the highest-precision atom-interferometry tests of fundamental physics worldwide.
Hogan leads the Stanford effort on MAGIS-100, a 100-meter atom-interferometric gradiometer at Fermilab designed to search for mid-band gravitational waves and ultralight dark matter using laser-cooled strontium atoms in free fall. His group also develops compact cold-atom gravimeters and gradiometers and explores large-momentum-transfer atom optics to push interferometer sensitivity toward tests of general relativity.
Kasevich is a pioneer of light-pulse atom interferometry, building cold-atom sensors of rotation, acceleration, and gravity that rival or exceed classical inertial instruments, and precision tests of general relativity and searches for dark matter and gravitational waves via large-scale atom interferometers (including MAGIS-100). His 2022 Nature paper demonstrated distributed quantum sensing with mode-entangled, spin-squeezed atomic states, extending entanglement-enhanced metrology to networks of separated sensors.
The Kovachy Group applies quantum wave properties of ultracold atoms to precision sensing. Primary focus: (1) Advanced large-momentum-transfer (LMT) atom interferometer pulse sequences using Bragg diffraction and Bloch oscillations to achieve record momentum splits of 100s of ℏk, enhancing sensitivity for fundamental physics tests; (2) MAGIS-100 collaboration — the 100 m-tall atom interferometer at Fermilab targeting gravitational waves in the mid-band complementary to LIGO/LISA, dark matter field searches, and tests of quantum mechanics at macroscopic scales; (3) Search for deviations from Newtonian gravity at micrometer range using atom-interferometric force sensing, and a new measurement of Newton's gravitational constant G; (4) Cryogenic optical cavity dark matter search (with Gabrielse and Geraci groups). David and Lucile Packard Fellow (2020), Paul Ehrenfest Best Paper Award 2020, NIST Precision Measurement Grant 2019. Member of CFP Northwestern and CIERA.
