Fig. 2: Landau-level formation.
From: Observation of supersymmetric pseudo-Landau levels in strained microwave graphene
Experimentally determined density of states (left panels) and spatially resolved mode intensity associated with the central peak centred at ω0 = 6.653 GHz (right panels, obtained by integrating the local density of states over the peak). The area of the circles corresponds to the intensity on the A sites (red) and B sites (blue). From top to bottom, the pseudomagnetic field strength β varies from 0 to 0.2. The grey dashed lines in the total density of states for β = 0.2 depict the expected pseudo-Landau level frequencies from coupled-mode theory. The formation of the 0th pseudo-Landau level proceeds continuously by transforming the zigzag edge states into bulk states while retaining the degeneracy (spectral weight) and sublattice polarisation (remaining confined on the A sublattice)
