Query: Quantum Magnetic Collapse   We study the thermodynamics of degenerate electron and charged vector boson
gases in very intense magnetic fields. In degenerate conditions of the electron
gas, the pressure transverse to the magnetic field $B$ may vanish, leading to a
transverse collapse. For W-bosons an instability arises because the
magnetization diverges at the critical field B_c = M_W^2/e. If the magnetic
field is self-consistently maintained, the maximum value it can take is of the
order of $2B_c/3$, but in any case the system becomes unstable and collapses.
