Extreme field physics and the 10/100 PW lasers at SIOM

The 10PW laser facility (SULF) is now in the commissioning phase and an 100PW laser station (SEL) is being built on the hard x-ray free electron laser facility (SHINE) in Shanghai. These facilities not only provide light intensities in the range of 10^21-23 W/cm^2 but also the opportunity to integrate the most powerful light sources in the optical and x-ray regimes. In this presentation, I will introduce the status of both facilities, including some primary results on laser-proton acceleration in SULF and recent progress & science cases of SEL, which mainly focuses on strong-field QED phenomena and high energy density physics. In additional, our recent theoretical and simulation work will also be discussed, on the spin related dynamics in extreme laser fields, the quantum vortex effect in QED scattering processes and so on.
