Anomalous domain wall condensation in a modified Ising chain
Gertian Roose, Laurens Vanderstraeten, Jutho Haegeman +1
We construct a one-dimensional local spin Hamiltonian with an intrinsically non-local, and therefore anomalous, global symmetry. The model is closely related to the…
Three-dimensional superconductors with hybrid higher order topology
Nick Bultinck, B. Andrei Bernevig, Michael P. Zaletel
We consider three dimensional superconductors in class DIII with a four-fold rotation axis and inversion symmetry. It is shown that such systems can exhibit higher order topology w…
Filling constraints on fermionic topological order in zero magnetic field
Nick Bultinck, Meng Cheng
We consider two-dimensional electron systems in zero magnetic field at fractional filling. For such systems a Lieb-Schultz-Mattis theorem applies, forbidding the existence of a tri…
Mapping topological to conformal field theories through strange correlators
Matthias Bal, Dominic J. Williamson, Robijn Vanhove +3
We extend the concept of strange correlators, defined for symmetry-protected phases in [You et al., Phys. Rev. Lett. 112, 247202 (2014)], to topological phases of matter by taking…
