摘要翻译：
在自洽平均涨落场近似下，计算了强耦合涨落偶极子系统的静态介电磁化率与温度的关系。结果与低温下的准电量子SrTiO3$定性一致。我们将该体系确定为{It量子临界准电态}，并提出了通过施加静水压力或杂质掺杂来实现{It量子临界准电态}的可能实验实现方法。

英文摘要：
  The temperature dependence of 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, SrTiO$_3$ in the low temperature regime. We identify this system as a {\it gaped quantum paraelectric} and suggest a possible experimental realization of a {\it quantum critical paraelectric} through the application of hydrostatic pressure or doping by impurity.
