From: Single-particle properties of topological Wannier excitons in bismuth chalcogenide nanosheets
Relative real-space probability densities of the exciton eigenstates \(|\varvec{Q}; 0_{\pm }; n, m \rangle\). The rows correspond, from top to bottom, to the first five dotted-line states of Fig. 4. In the left column, \(\varvec{Q} = \varvec{0}\) and we take appropriate linear combinations resulting in hydrogen-like orbitals. The right column corresponds to \(\varvec{Q}\) along the x-direction, with \(Q = {0.7}\,{\hbox {nm}^{-1}}\). The values of n and m are indicated in each plot, as well as the orbital name in the standard notation.
