Ferro-lattice-distortions and charge fluctuations in superconducting LaO${}_{1-x}$F${}_x$BiS${}_2$

A. Athauda, C. Hoffman, Y. Ren +5

Competing ferroelectric and charge density wave phases have been proposed to be present in the electron-phonon coupled LaO${}_{1-x}$F${}_x$BiS${}_2$ superconductor. The lattice insta…
