Hello! Someone mentioned to me about about a way to produce in flight neutralization of atomic/molecular beams by making the beam pass through a gas of particles produce through ablation (and not use a neutralization cell as it is often done). From my understanding, basically, one has a region where they ablate some material, and the beam of interest passes through the plasma created during the ablation and it gets neutralized. They mentioned it was a group from Japan (not totally sure), but I couldn't find that online. Does anyone know anything about this and point me towards a paper? Thank you!

From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...
