http://arxiv.org/pdf/1203.5699.pdf > The paper you cite talks about the changing masses of ⍴ and A mesons under strong magnetic fields. It does not talk about meson condensation. It does mention some interesting points, however: - "It is known that cosmic space objects called magnetars or neutron stars possess magnetic field in their cores equal to ∼ 1 MeV. [sic]" - "The values of magnetic fields in non-central heavy-ion collisions can reach up to ... ~ 290 MeV^2" Another paper indicates that in the cores of neutron stars [2], where the magnetic field is ~ 10^15 Tesla, ⍴- mesons *might* condense (the ⍴ meson is only slightly heavier than the π- meson, which is what we need for muons). We have a number of degrees of freedom to pin down to get any closer to our meson condensation: - What is the strength of the local magnetic field in a small volume in DGT's reactor? Is it in the twilight zone? Is it actually pretty small? - What is the effect of an extreme magnetic field on the condensation of π mesons? Does it enhance it? Does it inhibit it? I get the sense it could go either way. - How does the environment in a small volume in DGT's reactor compare to that in the core of a neutron star? Is it as extreme? Is it perhaps less extreme? I'm going to guess that we don't even have a prima facie case to become interested in the possibility of meson condensation at this point.
