Fig. 5: Various skin effects under different boundary configurations.
From: Experimental probe of point gap topology from non-Hermitian Fermi-arcs
a–c Calculated mode profiles (second and third rows, shown in magenta) under different boundary configurations (first row) at two selected \({k}_{z}\) (labeled on the left) illustrate hybrid skin effect (SE) (second row) and geometry-dependent skin effect (GDSE) (third row), respectively. In the first row, the yellow and blue lines represent two types of zigzag boundaries, the orange line represents the armchair boundary, and the gray line represents an arbitrary boundary.
