Charge density waves with nontrivial orbital textures in rare earth tritellurides

Year: 2024

Type: article

Abstract: Recent experiments on the rare-earth tritellurides $R$Te${}_{3}$ reveal unconventional collective modes in the charge density wave (CDW) state, suggesting symmetry breaking beyond that imposed by the CDW wave vector. Here, the authors develop a CDW Ginzburg-Landau theory that incorporates nontrivial orbital order, allowing for solutions in which two CDWs with distinct orbital characters coexist. The resulting CDW pattern exhibits an orbital texture that can break mirror and/or inversion symmetry.
