researchers are studying the properties of strontium titanate, also known as srto3, under various conditions. some studies have found that applying terahertz fields or strain can induce ferroelectricity in this material, which is normally a quantum paraelectric. the exact mechanisms and outcomes of these experiments are still being explored, with different studies reporting different effects, including the creation of metastable ferroelectricity and the manipulation of phonon-polaritons.
