We study nuclear spin frequency shifts in a $^{3}\mathrm{He}\text{\ensuremath{-}}^{129}\mathrm{Xe}$ comagnetometer caused by spin polarization of $^{3}\mathrm{He}$. We use stemless cylindrical cells to systematically vary the cell geometry and separately measure the cell shape-dependent and shape-independent frequency shifts. We find that a certain aspect ratio for a cylindrical cell cancels the dipolar effects of $^{3}\mathrm{He}$ magnetization in the regime of fast spin diffusion. Using this…

Dynamical Effects of the Dipolar Field Inhomogeneities in High-Resolution NMR: Spectral Clustering and Instabilities

In high-resolution NMR in liquids, for ``large'' nuclear spin magnetization (e.g., water at equilibrium in high field, optically polarized ${}^{129}\mathrm{Xe}$, etc.), the interplay of spatial

Comment on "New limit on Lorentz-invariance- and CPT-violating neutron spin interactions using a free-spin-precession (3)He-(129)Xe comagnetometer".

The authors use a classical result for the magnetic field created by a uniform magnetization to analyze the effects of magnetic interactions between He and Xe nuclear spins but the actual interaction is much weaker, calling into question the results of their analysis setting limits on Lorentz invariance.

Frequency shifts in noble-gas comagnetometers

Polarized nuclei are a powerful tool in nuclear-spin studies and in the search for physics beyond the standard model. Systems which compare two nuclear species have thus far been limited by anomalous

Nuclear spin-spin coupling in a van der Waals-bonded system: xenon dimer.

A first-principles computational study of the prototypic van der Waals-bonded xenon dimer, where the spin-spin coupling between two magnetically non-equivalent isotopes, J((129)Xe - (131) Xe), is observable, demonstrates cross-coupling effects between relativity and electron correlation for this property.
