Abstract

Strain engineering is a powerful tool to shape the dispersion of Dirac materials. Here we use a honeycomb lattice of coupled polariton micropillars to implement tilted photonic Dirac cones, including type-III cones. To do so, we introduce a spatial asymmetry in the hopping of photons in the x and y directions of the lattice. When the hopping presents a spatial gradient, an artificial gauge field for photons is engineered, and photonic Landau levels are observed.
