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…

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

TLDR
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.

TLDR
The new ‘helium method’ for estimations of nuclear dipole moments was successfully tested and the weak intermolecular interactions observed on the 3He and 129Xe and 131Xe shielding in the gaseous mixtures with Xe, CO2 and SF6 are demonstrated.

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.

TLDR
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.

TLDR
The NMR properties (chemical shift and spin-spin coupling constants) of (129)Xe in covalent compounds and weakly bound complexes have been investigated by DFT methods including relativistic effects, and small but non-negligible through-space coupling constants are predicted.
