| Abstract: | The temperature dependence of the static dielectric susceptibility of a system with strongly coupled fluctuating dipoles is calculated within a self-consistent mean fluctuation field approximation. Results are qualitatively in good agreement with a quantum paraelectric SrTiO3 in the low temperature regime. We identify this system as a gapped quantum paraelectric and suggest a possible experimental realization of a quantum critical paraelectric through the application of hydrostatic pressure or doping by impurity. |
