Liquid Metal (Sirius XM) Guy were severed from the channel as part of XM Liquid Metal's signoff. The Hard Attack play list has also been changed, featuring acts that were once heard on the former XM channel Squizz. Mercury has been replaced by Beyond the Pit, which airs in the middle of the night, instead of its former evening drive time slot. As part of the Sirius XM update, Sirius 27 Hard Attack was renamed Liquid Metal (taking the name of the channel that was on XM channel 42). Original subscribers to Sirius and XM have been disappointed because the title change, and others
Fermi liquid theory of the total weight is in a broad "incoherent background", corresponding to the strong effects of interactions on the fermions at short time-scales. The distribution of particles (as opposed to quasiparticles) over momentum states at zero temperature still shows a discontinuous jump at the Fermi surface (as in the Fermi gas), but it does not drop from 1 to 0: the step is only of size formula_12. In a metal the resistivity at low temperatures is dominated by electron-electron scattering in combination with umklapp scattering. For a Fermi liquid, the resistivity from this mechanism varies as formula_27, which is often
