News

• [08 Mar 2025]

  Communications Physics publishes our recent work Frequency shift caused by nonuniform field and boundary relaxation in magnetic resonance and comagnetometers.

In this work, we proposed a model to analyze the systematic error caused by nonuniform field and boundary relaxation in an NMR gyroscope.

• [25 Jan 2025]

  IEEE Sensors Journal publishes our recent work Planar Coil Design for Nuclear Magnetic Resonance Gyroscope Using Genetic Algorithm.

In this work, we designed and implemented a planar coil design for an NMR gyroscope using a genetic algorithm.

• [06 Jan 2025]

  Physical Review A publishes our recent work Magnetic-resonance linewidth of alkali-metal vapor in the unresolved Zeeman-resonance regime.

In this work, we developed the theory of magnetic-resonance linewidth of alkali-metal vapor in the unresolved Zeeman-resonance regime.

• [24 Jan 2024]

  Physical Review Applied publishes our recent work Stability improvement of nuclear magnetic resonance gyroscope with self-calibrating parametric magnetometer.

In this work, we improved the stability of nuclear magnetic resonance gyroscope by using a self-calibrating parametric magnetometer. With this method, the Allan deviation of 0.2 deg/hr for datasets of 8h, or 0.02deg/hr for the best approximately 5000 s data set was achieved.

• [10 Jan 2023]

  Physical Review Letters publishes our recent work Stable Atomic Magnetometer in Parity-Time Symmetry Broken Phase.

In this work, we experimentally observed the PT transition of diffusive nuclear spins, and demonstrated a PT-transition assisted stable magnetometer, which could be useful in measurement weak magnetic fields.

• [17 August 2021]

  Physical Review A publishes our recent work Spin-polarization dependence of the Rb-Xe spin-exchange optical pumping process.

In this work, we experimentally measured the spin-exchange pumping rate between Rb-Xe atoms under different optical pumping conditions of Rb atoms.

• [29 April 2020]

  Physical Review Letters publishes our recent collaboration work Sensing Individual Nuclear Spins with a Single Rare-Earth Electron Spin.

  The experiment part of this work was completed in the Stuttgart group. We did theoretical analysis of the spin dynamics in this work.

• [26 March 2020]

  Physical Review Letters publishes our recent work Magnetic Noise Enabled Biocompass.
