Geodesic geometry of 2+1-D Dirac materials subject to artificial, quenched gravitational singularities
The spatial modulation of the Fermi velocity for gapless Dirac electrons in quantum materials is mathematically equivalent to the problem of massless fermions on a certain class of curved spacetime manifolds. We study null geodesic lensing through these manifolds, which are dominated by curvature si...
