Algebraic localization of Wannier functions implies Chern triviality in non-periodic insulators
Jianfeng Lu, Kevin D. Stubbs
For gapped periodic systems (insulators), it has been established that the insulator is topologically trivial (i.e., its Chern number is equal to ) if and only if its Fermi proj…

Algebraic localization implies exponential localization in non-periodic insulators
Jianfeng Lu, Kevin D. Stubbs
Exponentially-localized Wannier functions are a basis of the Fermi projection of a Hamiltonian consisting of functions which decay exponentially fast in space. In two and three spa…
