Spin Relaxometry with Solid-State Defects: Theory, Platforms, and Applications
Ruotian Gong, Alex L. Melendez, Guanghui He +3
Spin relaxometry using solid-state spin defects, such as the diamond nitrogen-vacancy (NV) center, probes dynamical processes by measuring how environmental fluctuations enhance th…
Probing Boron Vacancy Defects in hBN via Single Spin Relaxometry
Alex L. Melendez, Ruotian Gong, Guanghui He +14
Spin defects in solids offer promising platforms for quantum sensing and memory due to their long coherence times and optical addressability. Here, we integrate a single nitrogen-v…
Quantum noise spectroscopy of superconducting dynamics in thin film BiSrCaCuO
Zhongyuan Liu, Ruotian Gong, Jaewon Kim +14
Characterizing the low-energy dynamics of quantum materials is crucial to our understanding of strongly correlated electronic states. Yet, it remains experimentally challenging to…
Probing Stress and Magnetism at High Pressures with Two-Dimensional Quantum Sensors
Guanghui He, Ruotian Gong, Zhipan Wang +15
Pressure serves as a fundamental tuning parameter capable of drastically modifying all properties of matter. The advent of diamond anvil cells (DACs) has enabled a compact and tabl…
Temperature dependent spin-phonon coupling of boron-vacancy centers in hexagonal boron nitride
Zhongyuan Liu, Ruotian Gong, Benchen Huang +9
The negatively charged boron-vacancy center () in hexagonal boron nitride (hBN) has recently emerged as a highly promising quantum sensor. Compared to th…
