Bulk-corner correspondence of time-reversal symmetric insulators: deduplicating real-space invariants
Sander H. Kooi, Guido van Miert, Carmine Ortix
The topology of insulators is usually revealed through the presence of gapless boundary modes: this is the so-called bulk-boundary correspondence. However, the many-body wavefuncti…
Extended Bloch theorem for topological lattice models with open boundaries
Flore K. Kunst, Guido van Miert, Emil J. Bergholtz
While the Bloch spectrum of translationally invariant noninteracting lattice models is trivially obtained by a Fourier transformation, diagonalizing the same problem in the presenc…
Boundaries of boundaries: a systematic approach to lattice models with solvable boundary states of arbitrary codimension
Flore K. Kunst, Guido van Miert, Emil J. Bergholtz
We present a generic and systematic approach for constructing D-dimensional lattice models with exactly solvable d-dimensional boundary states localized to corners, edges, hinges a…
Inversion-symmetry protected chiral hinge states in stacks of doped quantum Hall layers
Sander H. Kooi, Guido van Miert, Carmine Ortix
We prove the existence of higher-order topological insulators with protected chiral hinge modes in quasi-two-dimensional systems made out of coupled layers stacked in an inversion-…
Higher-order topological insulators protected by inversion and rotoinversion symmetries
Guido van Miert, Carmine Ortix
We prove the existence of higher-order topological insulators in: {\it i}) fourfold rotoinversion invariant bulk crystals, and {\it ii}) inversion-symmetric systems with or without…
Dislocation charges reveal two-dimensional topological crystalline invariants
Guido van Miert, Carmine Ortix
We identify a one-to-one correspondence between the charge localized around a dislocation characterized by a generic Burgers vector and the Berry phase associated with the electron…
Excess charges as a probe of one-dimensional topological crystalline insulating phases
Guido van Miert, Carmine Ortix
We show that in conventional one-dimensional insulators excess charges created close to the boundaries of the system can be expressed in terms of the Berry phases associated with t…
