Cluster-correlation expansion for studying decoherence of clock transitions in spin baths
Geng-Li Zhang, Wen-Long Ma, Ren-Bao Liu
The clock transitions (CTs) of central spins have long coherence times because their frequency fluctuations vanish in the linear order of external field noise (such as Overhauser f…

Hyperfine spectroscopy in a quantum-limited spectrometer
S. Probst, G. L. Zhang, M. Rančić +12
We report measurements of electron spin echo envelope modulation (ESEEM) performed at millikelvin temperatures in a custom-built high-sensitivity spectrometer based on superconduct…
