Abstract: The quark gluon plasma (QGP), which once occupied the early universe, can be re-created in relativistic heavy ion collision (HIC) experiments. The last two decades can be called the electronics era of QGP physics because most of the properties of QGP were retrieved through analyzing the phase-space information of detected charged particles. Very recently, the success of detecting the spin polarization of hadrons in HIC experiments enables us to extract the spin information (angular momenta transfer, spin transport, etc) of QGP and leads us to a new era of QGP spintronics. I will discuss some theoretical issues regarding the spintronics of QGP including (1) the vortical structure of QGP and how it is reflected in spin polarization of hadrons, (2) the kinetic and hydrodynamic tools to describe the spin transport in QGP, (3) some puzzles (and the recent efforts to resolve them) in explaining the current experimental data.
