Wittweg works on the XENONnT liquid-xenon dark matter experiment, focusing on detector calibration, low-background techniques and rare-event/dark-matter analyses; recently joined Imperial and is establishing a new noble-liquid detector research programme.
Wolf works on trapped-ion quantum sensing, using the motional degrees of freedom of single ions and small crystals as transducers for weak electric fields and forces, together with non-classical motional states (squeezed and Fock states) to enhance the achievable sensitivity. The broader agenda is to use trapped ions as a testbed for fundamental measurement limits — quantum-enhanced amplification of small displacements, quantum non-demolition readout of motion — with an eye to applications in electric-field metrology and searches for new physics. 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 — trapped-ion motional sensing is the cleanest available platform for demonstrating the entanglement-enhanced scaling that NV ensembles at pT/sqrt(Hz) approach only in the shot-noise-limited regime. Early-career independent PI within the Quantum Control Laboratory; smaller group, higher autonomy.
Studies molecular gas and the interstellar medium in galaxies using radio and millimeter interferometry (e.g., ALMA, CARMA).
PREFERRED. Wong's research centers on quantum and nonlinear optics, particularly high-flux, high-purity polarization-entangled and pure-state single-photon sources (including the Sagnac-interferometer entanglement source later flown on a Chinese quantum-communication satellite) for quantum key distribution and quantum information processing. By his own account he is approaching retirement in the near future, so his continued availability for a postdoc search should be confirmed directly.
Wood works on NV centres in physically rotating diamond, a niche he essentially created: by spinning the crystal at tens of kHz he has demonstrated spin-rotation coupling, geometric phases and rotationally-induced pseudo-fields on NV ensembles, and used the rotating frame as a resource for noise-averaging and for gyroscopy. The group also works on conventional bulk NV magnetometry, dynamical decoupling sequence design and nuclear-spin bath engineering. 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 rotating-frame protocols are a direct attempt to extend the DEER/T1-relaxometry toolbox — normally applied to static ensembles at pT/sqrt(Hz) — into a regime where the sensor itself is in motion, with obvious relevance to inertial sensing and to averaging away static field gradients. Early-career PI, smaller group; a good option for a candidate wanting substantial independence.
Wrachtrup is a founder of NV-centre quantum sensing: single-spin and ensemble magnetometry, nanoscale/single-molecule NMR and ESR, nuclear-spin registers, scanning-probe quantum-materials imaging, and programmable diamond nanosensors for chemistry and biology. His group actively recruits postdocs across NV sensing and quantum technology. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work is the reference point, extending DEER/nano-NMR toward single-molecule and cryogenic regimes.
Develops multidimensional coherent spectroscopy methods, including label-free multidimensional optical imaging/contrast techniques applied to cancerous tissue and nanoscale heterostructures.
Wurm's group builds and exploits large liquid-scintillator neutrino detectors, principally JUNO (reactor neutrinos, mass ordering) plus low-energy solar and geo-neutrino physics; work spans scintillator chemistry and optical purity, photosensor characterization, and reconstruction. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), included as a detector-instrumentation pivot -- the transferable content is ultra-low-noise photon counting and calibration at scale, not spin physics.
Wyatt studies the structure, composition and dynamical evolution of circumstellar debris discs (using ALMA, Herschel and JWST imaging) as tracers of hidden planetary systems, linking dust production, planetesimal collisions and planet-disc interactions to the broader picture of planet formation.
Wysocki develops quantum-cascade-laser-based spectroscopic sensing systems, including external-cavity QCLs, dispersion spectroscopy, and mid-IR dual-comb spectrometers, that routinely reach fundamental quantum-noise detection limits for trace-gas sensing; applications span atmospheric/environmental monitoring, drone-based methane leak detection, industrial process control, and human breath-based metabolic/medical diagnostics.
