Description
The correlation of dynamical density fluctuation has been investigated within the scope of the Mueller-Israel-Stewart theory. The dynamic structure of the density fluctuation without the presence of the magnetic field shows three Lorentzian peaks. The central Rayleigh peak is surrounded by two Brillouin peaks symmetrically situated around the Rayleigh peak. But with the presence of an external constant magnetic field, the structure factor shows four peaks identified as one Rayleigh peak, two Brillouin peaks, and one peak due to the coupling of the magnetic field with the fluid velocity. The emergence of the extra peak due to the coupling can play an important role in measuring the relaxation of the system.
