摘要:Under suitable non-equilibrium conditions QCD plasma can develop plasma instabilities, i.e. exponential
growth of some modes of the plasma. It has been argued that these instabilities can
play a significant role in the thermalisation of the plasma in heavy-ion collision experiments. We
study the instability in SU(2) plasmas using the hard thermal loop effective lattice theory, which
is suitable for studying real-time evolution of long wavelength modes in the plasma. We observe
that under suitable conditions the plasma can indeed develop an instability which can grow to a
very large magnitude, necessary for the rapid thermalisation in heavy-ion collisions.
