Ghiasi's Quantum Spintronics (QuSpin) Lab studies spin transport and magnetism in 2D and van der Waals materials, and — in close collaboration with the van der Sar group — pioneered a diamond-membrane dry-transfer technique that brings NV-ensemble ensembles into direct nanoscale contact with 2D antiferromagnets (e.g., CrSBr) to quantitatively image monolayer-thickness-dependent magnetic stray fields. This complements the well-established line of NV-ensemble quantum sensing experiments (DEER, NMR, T1-relaxometry) that reach pT/sqrt(Hz)-class sensitivities, extending the toolbox toward mechanical and single-atom/single-spin readout.
