Query: Magnetohydrodynamic shocks in a dissipative quantum plasma with
  exchange-correlation effects   We investigate the nonlinear propagation of multidimensional magnetosonic
shock waves (MSWs) in a dissipative quantum magnetoplasma. A macroscopic
quantum magnetohydrodynamic (QMHD) model is used to include the quantum force
associated with the Bohm potential, the pressure-like spin force, the exchange
and correlation force of electrons, as well as the dissipative force due to the
kinematic viscosity of ions and the magnetic diffusivity. The effects of these
forces on the properties of arbitrary amplitude MSWs are examined numerically.
It is found that the contribution from the exchange-correlation force appears
to be dominant over those from the pressure gradient and the other similar
quantum forces, and it results into a transition from monotonic to oscillatory
shocks in presence of either the ion kinematic viscosity or the magnetic
diffusivity.
