Symmetric approximant formalism for statistical topological matter
R. Johanna Zijderveld, Adam Yanis Chaou, Isidora Araya Day +1
The standard approach to characterizing topological matter, computing topological invariants, fails when the symmetry protecting the topological phase is preserved only on average…

Scattering theory of higher order topological phases
R. Johanna Zijderveld, Isidora Araya Day, Anton R. Akhmerov
The surface states of intrinsic higher order topological phases are protected by the spatial symmetries of a finite sample. This property makes the existing scattering theory of to…
