Concepts used: Hamiltonian, eigenvalues, dispersion.
Some of my articles are using Dirac points:
- Dirac point in a photonic system (microcavity): Experimental investigation of a non-Abelian gauge field in 2D perovskite photonic platform
- Massless and massive Dirac Hamiltonians used in semiclassical equations of motion of a particle: Universal semiclassical equations based on the quantum metric for a two-band system
- Non-Hermiticity transforms a Dirac point into a pair of exceptional points: Experimental measurement of the divergent quantum metric of an exceptional point
