Topological Order and Absence of Band Insulators at Integer Filling in Non-Symmorphic Crystals
S. A. Parameswaran, Ari M. Turner, Daniel P. Arovas +1
Band insulators appear in a crystalline system only when the filling -- the number of electrons per unit cell and spin projection -- is an integer. At fractional filling, an insula…
Stability of Weyl metals under impurity scattering
Zhoushen Huang, Tanmoy Das, Alexander V. Balatsky +1
We investigate the effects of bulk impurities on the electronic spectrum of Weyl semimetals, a recently identified class of Dirac-type materials. Using a -matrix approach, we st…
Edge States, Entanglement Spectra, and Wannier Functions in Haldane's Honeycomb Lattice Model and its Bilayer Generalization
Zhoushen Huang, Daniel P. Arovas
We study Haldane's honeycomb lattice model and a bilayer generalization thereof from the perspective of edge states, entanglement spectra, and Wannier function behavior. For the mo…
Entanglement spectrum and Wannier center flow of the Hofstadter problem
Zhoushen Huang, Daniel P. Arovas
We examine the quantum entanglement spectra and Wannier functions of the square lattice Hofstadter model. Consistent with previous work on entanglement spectra of topological band…
