Charge density wave induced gapped nodal line
Sergey Alekseev, Lei Chen, Jennifer Cano
We investigate the interplay between charge density wave (CDW) order and topological nodal-line states in square-net materials. Our Ginzburg-Landau theory predicts a CDW instabilit…

Uncovering the Hidden Ferroaxial Density Wave as the Origin of the Axial Higgs Mode in RTe
Birender Singh, Grant McNamara, Kyung-Mo Kim +24
The recent discovery of an axial amplitude (Higgs) mode in the long-studied charge density wave (CDW) systems GdTe and LaTe suggests a heretofore unidentified hidden order.…

Charge density-waves with non-trivial orbital textures in rare earth tritellurides
Sergey Alekseev, Sayed Ali Akbar Ghorashi, Rafael M. Fernandes +1
Motivated by recent experiments reporting unconventional collective modes in the charge density-wave (CDW) state of rare-earth tritellurides Te, we derive from a multi-orbit…
