Displacement eigenfunctions corresponding to the three largest peaks in Fig. 1. The eigenfunctions were multiplied by the square root of the background density to improve the visibility and as the square of this quantity is proportional to the energy density. Colors indicate the different modes. Solid lines indicate the real part, and dashed lines illustrate the imaginary part. For ease of display, the scaled eigenfunctions were normalized to unity at the bottom boundary.
