Charge order induced Dirac pockets in the nonsymmorphic crystal <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msub><mml:mi mathvariant="normal">TaTe</mml:mi><mml:mn>4</mml:mn></mml:msub></mml:math>
The interplay between charge order (CO) and nontrivial band topology has spurred tremendous interest in understanding topological excitations beyond the single-particle description. In a quasi-one-dimensional nonsymmorphic crystal ${\mathrm{TaTe}}_{4}$, the ($2\mathrm{a}\ifmmode\times\else\texttimes\fi{}2\mathrm{b}\ifmmode\times\else\texttimes\fi{}3\mathrm{c}$) charge ordered ground state drives the system into a space group where the symmetry indicators feature the emergence of Dirac …
