#Magnons #Photons and #Bose -Einstein Moments.

This will/should/maybe/certainly reach far beyond data storage densities and energies. Its *room temperature* quantum manipulation OR magic OR both.

A team from the University of Konstanz (Germany near Switzerland) has had a bit of a WTF "moment"...

They snapped some light onto some iron crystals and had a beer fueled lunch I hope.

"" despite the substantial volume of research concerning the optical activation of any coherent collective excitation (phonons, magnons, plasmons, and polaritons) in solids, neither a modification of the spectrum ... nor a coupling be-
tween high-momentum and gamma-point modes at fundamental timescales has been reported. """

ICYMI - in 2022 a research team including Lindsay Greer @Cambridge_Uni discovered a potential new method for making the #magnets used in wind turbines and electric cars (without using #RareEarths): creating #tetrataenite.

Hey, any #researchers (#physics, #materials science, etc) doing #research on magnetic materials [#magnetism]? I'd like your take on the prospect of #tetrataenite as an alternative to #neodymium #magnets. My understanding is that the theoretical magnetic energy product is about 80% that of available neodymium magnets, but that raises the question of how much realizable magnetic energy products might approach theoretical.
