Group Theory Analysis to Study Phase Transitions of Quasi-2D Sr$_{3}$Hf$_{2}$O$_{7}$
We present an $ab-initio$ study performed in the framework of density functional theory, group-subgroup symmetry analysis and lattice dynamics, to probe the octahedral distortions, which occur during the structural phase transitions of the quasi-2D layered perovskite Sr$_{3}$Hf$_{2}$O$_{7}$ compound...
