This article is the shit. More of wikipedia should be like this, well-written introductions to high-level academic topics complete with graphics and a little math. Things like this makes wikipedia far superior to a traditional encyclopedia. 134.154.254.125 (talk) 21:29, 14 June 2010 (UTC)LivingAlchemist
Atomic magnetometer
[edit]Michio Kaku calls this an atomic magnetometer.

change direction?
[edit]the collision "causing the atoms to precess in opposite directions"? seems very weird, any reference? Jackzhp (talk) 18:23, 14 October 2013 (UTC) There's a background magnetic field, so the electron with spin pointed in whatever direction will precess around the direction of the B field. When the spin of that electron is flipped in the spin exchange interaction, its direction of precession also reverses.
conserves total angular momentum
[edit]I must be missing something here, but in that first spin exchange, it shows the total angular momentum F=I+J going from 1,1 to 2,1 for atoms A and B. In my head that looks like an electron spin has flipped on atom A but nothing happened on atom B, which wouldn't conserve total angular momentum. Exactly what angular momentum quantity is being conserved? Exactly what does the interaction do? I've seen a terse reference to the projection of the angular momentum (m_Fz?) that is conserved? I've read that these fast interactions only mess with electron spin, so I've assumed all nuclear spins stay the same in the above.
SERF comparison figure needs improvements
[edit]The figure that compares the performances of SERF with other magnetometers is not clear. There are three lines of different colours, with no legend to explain what they mean. I suppose that the orange one is for SERF, but there is no info about the other two so I cannot even edit that figure. Please add a legend to the figure. — Preceding unsigned comment added by Leodymium (talk • contribs) 09:23, 24 July 2022 (UTC)
