Two-dimensional exciton superposition states with Dirac cone dispersion laws

Our review paper is dedicated to studies of two-dimensional (2D) Wannier–Mott excitons in transition metal dichalcogenides and 2D magnetoexcitons in GaAs-type quantum wells subjected to the action of a strong perpendicular magnetic field, which both revealed the Dirac cone dispersion laws. It is sho...
