Emergence of central mode in the paraelectric phase of ferroelectric perovskites

Original language description

THz-range dielectric spectroscopy and first-principle-basede effective-Hamiltonian molecular dynamics simulations were employed to elucidate the dielectric response in the paraelectric phase of(Ba,Sr)TiO3 solid solutions. Our analysis suggests a crossover between two regimes a higher-temperature regime goverened by the soft-mode only versus a lower-temperature regime exhibiting a coupled soft mode/central mode dynamics.
