Zero dimensional exciton-polaritons
The cover picture from the article  shows, in the left parts of the three diagrams, the measured photoluminescence intensity as a function of energy and emission angle for a 3 μm (left diagram), 9 μm (middle diagram) and 19 μm-diameter quasi-circular mesa (right diagram). The white lines are the energy dispersions of 2D polariton modes. For clarity, intensities above 1485 meV have been multiplied by a constant factor, as indicated. The right parts of the diagrams contain intensity plots of the simulated polariton spectral density for cylindrical mesas of the same diameters, yielding very good quantitative agreement of the 0D polariton states in the circular mesas. This confirms the coexistence of 0D and 2D microcavity polaritons in these semiconductor structures.
