Description
We employ topological concepts to study chiral edge modes in two-dimensional plasmas. By approximating the plasma as a fluid we calculate the topological invariant of
its Fourier-space bands, which are the dispersion relations of waves in the bulk of the system. Furthermore, calculation of possible wave-forms propagating in a single
direction at the boundary of the system allows for a principle of bulk-edge correspondence, where their signed number is fixed by the topology of the bulk. Using
various electric potential configurations, we aim to produce protected waves in the terahertz-frequency range.
