Nature Photonics, Published online: 23 April 2024; doi:10.1038/s41566-024-01412-3Strain-engineered pseudomagnetic fields realized in two-dimensional photonic crystals induce flat-band Landau levels at discrete energies as well as chiral edge states. The high density of states and high degeneracy of the flat bands has implications for both on-chip and...
