Nanodiamond sensing in dynamic environments with fast-tracking through four-point positioning
Guoli Zhu, Ming-Zhong Ai, Zhiyu Zhao +8
Nitrogen-vacancy (NV) centers in nanodiamonds are excellent nanoscale sensors for measuring parameters such as temperature, magnetic field, and viscosity in complex fluidic environ…
Diamond-based sensing of stray fields from the bulk of thin-film magnets via nano-indentation
Ming-Zhong Ai, Kang-Yuan Liu, Biao Zhang +8
Measurement of the magnetization in the bulk of thin-film or two-dimensional materials is important for understanding their intrinsic properties without the complications from edge…
Nanodiamond-based spatial-temporal deformation sensing for cell mechanics
Yue Cui, Weng-Hang Leong, Guoli Zhu +2
Precise assessment of the mechanical properties of soft biological systems at the nanoscale is crucial for understanding physiology, pathology, and developing relevant drugs. Conve…
Measurement of single-cell elasticity by nanodiamond-sensing of non-local deformation
Yue Cui, Weng-Hang Leong, Chu-Feng Liu +5
Nano-indentation based on, e.g., atomic force microscopy (AFM), can measure single cell elasticity with high spatial resolution and sensitivity, but relating the data to cell mecha…
Zero-field magnetometry using hyperfine-biased nitrogen-vacancy centers near diamond surfaces
Ning Wang, Chu-Feng Liu, Jing-Wei Fan +7
Shallow nitrogen-vacancy (NV) centers in diamond are promising for nano-magnetometry for they can be placed proximate to targets. To study the intrinsic magnetic properties, zero-f…
Ultra-sensitive hybrid diamond nanothermometer
Chu-Feng Liu, Weng-Hang Leong, Kangwei Xia +6
Nitrogen-vacancy (NV) centers in diamond are promising quantum sensors for their long spin coherence time under ambient conditions. However, their spin resonances are relatively in…
Nanometer-precision non-local deformation reconstruction using nanodiamond orientation sensing
Kangwei Xia, Chu-Feng Liu, Weng-Hang Leong +5
Information of material deformation upon loading is critical to evaluate mechanical properties of materials in general, and key to understand fundamental mechano-stimuli induced re…
Phase transitions in sequential weak measurements
Wen-Long Ma, Ping Wang, Weng-Hang Leong +1
Quantum measurements and phase transitions are seemingly uncorrelated topics, but here we show that phase transitions occur in sequential quantum measurements. We find that the pro…
Magnetic criticality-enhanced hybrid nanodiamond-thermometer under ambient conditions
Ning Wang, Gang-Qin Liu, Weng-Hang Leong +10
Nitrogen vacancy (NV) centres in diamond are attractive as quantum sensors owing to their superb coherence under ambient conditions. However, the NV centre spin resonances are rela…
Localized in-gap state in a single electron doped Mott insulator
Weng-Hang Leong, Shun-Li Yu, T. Xiang +1
Motivated by the recent atomic-scale scanning tunneling microscope (STM) observation for a spatially localized in-gap state in an electron doped Mott insulator, we evaluate the loc…
Effects of the spin-orbital coupling on the vacancy-induced magnetism on the honeycomb lattice
Weng-Hang Leong, Shun-Li Yu, Jian-Xin Li
The local magnetism induced by vacancies in the presence of the spin-orbital interaction is investigated based on the half-filled Kane-Mele-Hubbard model on the honeycomb lattice.…
