Fermi surface geometry and momentum dependent electron-phonon coupling drive the charge density wave in quasi-1D ZrTe $3$

Josu Diego, Matteo Calandra

ZrTe $_{3}$ is a prototypical quasi-one-dimensional compound undergoing a charge density wave transition via a very sharp Kohn anomaly in phonon momentum space. While Fermi surface ge…

First-order phase transition driven by competing charge-order fluctuations in 1T'-TaTe $_{2}$

S. K. Mahatha, A. Kar, J. Corral-Sertal +20

First-order phase transitions, characterized by a discontinuous change in the order parameter, are intriguing phenomena in condensed matter physics. However, the underlying, materi…

Phonon collapse and van der Waals melting of the 3D charge density wave of VSe $_{2}$

Josu Diego, A. H. Said, S. K. Mahatha +7

Among transition metal dichalcogenides (TMDs), VSe $_{2}$ is considered to develop a purely 3-dimensional (3D) charge-density wave (CDW) at T $_{C D W}$ =110 K. Here, by means of high res…
