Bakr pioneered quantum gas microscopy, imaging individual atoms in Hubbard-regime optical lattices with single-site resolution to directly visualize charge, spin, and polaronic correlations in strongly correlated many-body systems, including recent work resolving itinerant spin polarons and the Nagaoka effect in triangular-lattice Hubbard systems. His single-particle/single-molecule-resolved imaging platforms are a borderline but relevant pivot into the quantum-sensing space via ultra-precise, quantum-limited detection of individual quantum particles; included here for review given the emphasis on cutting-edge spatial resolution rather than sensing per se.
