Review of Progress in Magnetorotational Instability

I will describe the current numerical and experimental approaches for magnetorotational instability which is believed to be the driving mechanism of angular momentum transport in magnetized accretion disk. In the recent computational study, the incorporation of fully anisotropic pressure tensor on hybrid-MHD simulation shows interesting properties in the kinetic regime with low collisionality. The phenomenon can also be investigated further by the laboratory MRI experiments, for example through the use of liquid Galinstan alloy (GaInSn). Unlike observations of astrophysical plasma, laboratory astrophysical experiments can be used to investigate MRI over broad range of parameters with direct diagnostics.
