We discovered a new interaction where Rubidium (Rb) spins influence Xenon (Xe) spin precession in NMR. This Rb spin "radiation damping" affects Xe spin relaxation and frequency, impacting precision measurements.

Area of Science:

  • Atomic, Molecular, and Optical Physics
  • Nuclear Magnetic Resonance (NMR) Spectroscopy
  • Quantum Metrology

Background:

  • Spin-exchange optical pumping is crucial for polarizing noble gas spins like Xenon (Xe).
  • Rubidium (Rb) vapor is often used as a magnetometer to detect Xe spin precession.
  • Conventional NMR systems utilize coils to generate magnetic fields and detect spin signals.

Purpose of the Study:

  • To investigate a novel interaction between Rb and Xe spin ensembles.
  • To characterize the influence of Rb spin precession on Xe spin dynamics.
  • To assess the impact of this interaction on the accuracy of NMR probes for fundamental physics searches.

Main Methods:

  • Utilizing spin-exchange optical pumping to polarize Rb and Xe spins simultaneously.

  • Employing Rb vapor as both a spin-polarizing medium and a magnetometer.
  • Operating Xe spins in both free-induction decay and self-oscillating modes.

    • Main Results:

    • Observed a new interaction where precessing Xe spins induce precession in Rb spins.
    • Demonstrated that Rb spin precession causes "radiation damping" on Xe spins, affecting transverse relaxation time and oscillating frequency.
    • Quantified the changes in Xe spin dynamics due to the Rb spin effect in both free-induction decay and self-oscillating modes.

    Conclusions:

    • The interaction between Rb and Xe spin ensembles introduces a significant "radiation damping" effect.
    • This effect impacts the accuracy of NMR probes used in searches for CPT- and Lorentz-invariance violations and new forces.
    • Addressing this Rb spin damping effect could improve the sensitivity and limits of fundamental physics experiments.
