© 2019 In an earlier work  we developed a holographic theory for the phase transition between bosonic symmetry-protected topological (SPT) states. This paper is a continuation of it. Here we present the holographic theory for fermionic SPT phase transitions. We show that in any dimension d, the critical states of fermionic SPT phase transitions has an emergent Z2T symmetry and can be realized on the boundary of a d+1-dimensional bulk SPT with an extra Z2T symmetry.
