论文摘要
我们表明,经过两个圆形极化驱动器的相互作用的两旋模型可以在合成维度中对相关拓扑阶段进行可行的实现。可观察到的拓扑可观察到动态驱动器之间的频率转换给出,这就是为什么我们将IT铸造为相互作用的拓扑转换器(ITFC)。 ITFC的特征是相互作用和合成维度的相互作用。这引起了惊人的拓扑现象,这些现象在非相互作用方面没有对应。通过计算拓扑相图作为相互作用强度的函数,我们预测频率转化的增强是ITFC相关拓扑响应的直接表现。
We show that an interacting two-spin model subjected to two circularly polarized drives enables a feasible realization of a correlated topological phase in synthetic dimensions. The topological observable is given by a quantized frequency conversion between the dynamical drives, which is why we coin it the interacting topological frequency converter (ITFC). The ITFC is characterized by the interplay of interaction and synthetic dimension. This gives rise to striking topological phenomena that have no counterpart in the noninteracting regime. By calculating the topological phase diagrams as a function of interaction strength, we predict an enhancement of frequency conversion as a direct manifestation of the correlated topological response of the ITFC.
