论文摘要
我们确定了铁电体中的骨气激发，这些激发从现象学Landau-Ginzburg-Devonshire理论中带来了电偶极子。 “ Ferron”准颗粒从非谐感和破碎的反转对称性的动作中浮现出来。与磁子相比，磁性的横向激发，相对于铁电阶，位移铁电的纤维在纵向上是纵向的。基于Ferron光谱，我们预测依赖温度的高电和电气性特性，电场 - 可 - 可调热和极化转运以及Ferron-Photon杂交。
We identify the bosonic excitations in ferroelectrics that carry electric dipoles from the phenomenological Landau-Ginzburg-Devonshire theory. The "ferron" quasi-particles emerge from the concerted action of anharmonicity and broken inversion symmetry. In contrast to magnons, the transverse excitations of the magnetic order, the ferrons in displacive ferroelectrics are longitudinal with respect to the ferroelectric order. Based on the ferron spectrum, we predict temperature dependent pyroelectric and electrocaloric properties, electric-field-tunable heat and polarization transport, and ferron-photon hybridization.
