Lattice dynamics and Raman spectrum of BaZrO3 single crystals
Constance Toulouse, Danila Amoroso, Cong Xin +7
BaZrO3 is a perovskite that remains in the simple cubic phase at all temperatures, hence with no first-order Raman-active phonon mode allowed by symmetry. Yet, it exhibits an inten…

Archetypal soft-mode driven antipolar transition in francisite Cu3Bi(SeO3)2O2Cl
Cosme Milesi-Brault, Constance Toulouse, Evan Constable +8
Model materials are precious test cases for elementary theories and provide building blocks for the understanding of more complex cases. Here, we describe the lattice dynamics of t…
