Edit:
They are observing https://en.wikipedia.org/wiki/Feshbach_resonance https://en.wikipedia.org/wiki/Feshbach_resonance in NaLi gas that has been cooled down to 1.8µK.
In a nutshell when the applied magnetic field is almost precisely 334.92 Gauss the NaLi molecules couple together a lot more than normal because the magnetic field affects the energy levels of the molecules (the electrons in the molecules). When the energy levels match then certain coupled states are far more likely to happen.
Previously this has been observed between atoms but not between molecules (NaLi)

- badcppdev 4y agoYes but likely that it's only relevant when the temperature is in in the micro kelvins and the effect of the magnetic field is not absolutely overpowered by the thermal energy in the system.
- 0134340 4y agoSo magnetic fields can induce resonance? I wonder how large this scales? I've long wondered if gravity is just fields inducing resonant/attractive states in host material, ie, particles, molecules, etc but these frequencies are just ones we can't pickup, can't induce or manipulate yet. Or is that totally obvious or just dumb? Yes, I know about gravitons somewhat, and admittedly I'm not that versed in physics, but could that be how the particles manifest in wave form, ie, at large scale?
