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.

Digonnet's group develops high-sensitivity fiber-optic sensors, especially resonant and interferometric fiber-optic gyroscopes engineered to approach fundamental (shot-noise/quantum) rotation-sensing limits, alongside specialty fiber lasers and amplifiers.

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.

Windpassinger's group works on cold neutral atoms as both a platform for fundamental light-matter physics and a deployable sensing technology. The fundamental line uses dysprosium -- the most magnetic element -- to study light propagation in dense dipolar media, where interatomic spacings fall below the optical wavelength and light-induced plus magnetic dipole-dipole interactions produce cooperative effects (superradiance, subradiance); controlled transport in optical dipole traps and microfocusing let them tune from single-atom to collective behaviour. The applied line builds ultracold-atom quantum sensors that survive outside the lab: atom interferometers and BEC sources flown in the Bremen drop tower, on sounding rockets, and on the ISS, aimed at inertial sensing, gravimetry and tests of fundamental constants under microgravity. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), this is the complementary 'cold and fragile but absolutely calibrated' end of the sensing spectrum; the group's real distinguishing asset for a postdoc is the space/microgravity engineering pipeline, which is rare. The group states it is continuously looking for motivated researchers and lists open positions via the PI.
