Spin polarization dynamics in the Bjorken-expanding resistive MHD background

Evolution of spin polarization in the presence external electric field is studied for collision energies $\sqrt{{s}_{\mathrm{NN}}}=27\text{ }\text{ }\mathrm{GeV}$ and $\sqrt{{s}_{\mathrm{NN}}}=200\text{ }\mathrm{GeV}$. The numerical analysis done perfect-fluid Bjorken-expanding resistive magnetohydrodynamic background novel results are reported. In particular, we show that plays a significant role competition between expansion dissipation.
