Tutorial: Computing topological invariants in two-dimensional photonic crystals
María Blanco de Paz, Chiara Devescovi, Geza Giedke +5
The field of topological photonics emerged as one of the most promising areas for applications in transformative technologies: possible applications are in topological lasers or qu…
Hall viscosity in quantum systems with discrete symmetry: point group and lattice anisotropy
Pranav Rao, Barry Bradlyn
Inspired by recent experiments on graphene, we examine the non-dissipative viscoelastic response of anisotropic two-dimensional quantum systems. We pay particular attention to elec…
Observation and control of maximal Chern numbers in a chiral topological semimetal
Niels B. M. Schröter, Samuel Stolz, Kaustuv Manna +13
Topological semimetals feature protected nodal band degeneracies characterized by a topological invariant known as the Chern number (C). Nodal band crossings with linear dispersion…
Evidence for an axionic charge density wave in the Weyl semimetal (TaSe4)2I
Johannes Gooth, Barry Bradlyn, Shashank Honnali +9
An axion insulator is a correlated topological phase, predicted to arise from the formation of a charge density wave in a Weyl semimetal. The accompanying sliding mode in the charg…
Multifold nodal points in magnetic materials
Jennifer Cano, Barry Bradlyn, M. G. Vergniory
We describe the symmetry protected nodal points that can exist in magnetic space groups and show that only 3-, 6-, and 8-fold degeneracies are possible (in addition to the 2- and 4…
Engineering Fragile Topology in Photonic Crystals: Topological Quantum Chemistry of Light
María Blanco de Paz, Maia G. Vergniory, Dario Bercioux +2
In recent years, there have been rapid advances in the parallel fields of electronic and photonic topological crystals. Topological photonic crystals in particular show promise for…
