HIGHLIGHTS
- who: Jun Mei from the DepartmentSouth China University of have published the article: Pseudo-time-reversal symmetry and topological edge states in two-dimensional acoustic crystals, in the Journal: Scientific Reports Scientific Reports
- what: In the Method section, the authors demonstrate that the spatial symmetry of the E1 and E2 representations can be utilized to construct pseudo-time-reversal symmetry. In the following, the authors demonstrate edge wave propagation around a specific type of imperfection: four sharp bends of the edge shown in Fig 5(b), which is constructed from the structure in Fig 4 . . .
