Fermi surface geometry and momentum dependent electron-phonon coupling drive the charge density wave in quasi-1D ZrTe
Josu Diego, Matteo Calandra
ZrTe 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
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…
