Twisted crystalline equivalence principle for interacting fermionic systems
Twisted crystalline equivalence principle. In interacting fermionic systems, the crystalline equivalence principle should be applied in a twisted way: spinless (spin- $1/2$ ) fermion…

General group super-cohomology classification conjecture for 3D FSPT phases
General group super-cohomology classification conjecture. Up to spatial dimension $d_{sp}=3$ , FSPT phases with symmetry $G_f=G_b\times \mathbb Z_2^f$ can be classified by
