Abstract: Abstract Symmetry-breaking instabilities in high- pressure phase transformation produce the counterintuitive phenomenon of “volume collapse” producing only shear radiation, with little, or no, volumetric component, even under conditions of full isotropy, and explain the mystery… read more here.

DOI: 10.1016/j.jssc.2020.121360
Abstract: Abstract We report powder diffraction data measured on SrRuO3 to pressures of 88 GPa at ambient temperature. The perovskite structure is found to persist up to the highest pressure measured, but the system undergoes a continuous transition… read more here.
