Pfaffian invariant identifies magnetic obstructed atomic insulators

Isidora Araya Day, Anastasiia Varentcova, Daniel Varjas +1

We derive a topological invariant that extends beyond symmetry eigenvalues and Wilson loops and classifies two-dimensional insulators with a symmet…

Topological defects in a double-mirror quadrupole insulator displace diverging charge

Isidora Araya Day, Anton R. Akhmerov, Daniel Varjas

We show that topological defects in quadrupole insulators do not host quantized fractional charges, contrary to what their Wannier representation indicates. In particular, we test…
