... The haloid compounds with perovskite-like structure undergo as a rule ferroelastic phase transitions (PT's) related to the soft modes of lattice vibrations. ... The analysis of the relationship between the susceptibility to external pressure at PT's from initial phase and the structural peculiarities has been carried out for some families of perovskite-like ferroelastics, namely: perovskites, elpasolites, antifluorites, compounds with the ordered ReO 3 structure and layered perovskites. ...
... Entropy, Acoustic, and Vorticity Mode Decomposition as an Initial Step in Nonlinear Acoustics Formulations . ... The idea that fluid dynamic disturbances can be decomposed into three fields goes back to Kirchhoff and to Chu and Kovasznay. The labeling of the three fields ensues from that, in the linear limit, the equations governing these fields correspond to thermal (entropy) diffusion, sound propagation, and vorticity diffusion. ...
