We employ the eigen microstate approach to explore the self-organized criticality (SOC) in two celebrated sandpile models, namely, the BTW model and the Manna model. In both models, phase transitions from the absorbing-state to the critical state can be understood by the emergence of dominant eigen microstates with significantly increased weights. Spatial eigen microstates of avalanches can be uniformly characterized by a linear system size rescaling. The first temporal eigen microstates reveal scaling relations in both models. Furthermore, by finite-size scaling analysis of the first eigen microstate, we numerically estimate critical exponents i.e., √(σ0 w1)/v1 ∝ LD and v1 ∝ LD(1-τs)/2. Our findings could provide profound insights into eigen states of the universality and phase transition in non-equilibrium complex systems governed by self-organized criticality.
