Controllable tunability of a Chern number within the electronic-nuclear spin system in diamond
Junghyun Lee, Keigo Arai, Huiliang Zhang +2
Chern numbers are gaining traction as they characterize topological phases in various physical systems. However, the resilience of the system topology to external perturbations mak…
Millimetre-scale magnetocardiography of living rats using a solid-state quantum sensor
Keigo Arai, Akihiro Kuwahata, Daisuke Nishitani +16
A key challenge in cardiology is the non-invasive imaging of electric current propagation occurring in the cardiovascular system at an intra-cardiac scale. A promising approach for…
Selective addressing of solid-state spins at the nanoscale via magnetic resonance frequency encoding
Huiliang Zhang, Keigo Arai, Chinmay Belthangady +2
The nitrogen-vacancy (NV) centre in diamond is a leading platform for nanoscale sensing and imaging, as well as quantum information processing in the solid state. To date, individu…
Fourier Magnetic Imaging with Nanoscale Resolution and Compressed Sensing Speed-up using Electronic Spins in Diamond
K. Arai, C. Belthangady, H. Zhang +5
Optically-detected magnetic resonance using Nitrogen Vacancy (NV) color centres in diamond is a leading modality for nanoscale magnetic field imaging, as it provides single electro…
Dressed-State Polarization Transfer between Bright & Dark Spins in Diamond
Chinmay Belthangady, N. Bar-Gill, L. M. Pham +4
Under ambient conditions, spin impurities in solid-state systems are found in thermally-mixed states and are optically "dark", i.e., the spin states cannot be optically controlled.…
