Electric polarization as a nonquantized topological response and boundary Luttinger theorem
We develop a nonperturbative approach to the bulk polarization of crystalline electric insulators in d≥1 dimensions. Formally, we define polarization via the response to background fluxes of both charge and lattice translation symmetries. In this approach, the bulk polarization is related to propert...
