论文摘要
当两个或多个发射器通过电磁场合作相互作用时,就会发生Dicke上级。从原子到量子点和有机分子,已经对这种集体光散射过程进行了广泛的研究。尽管进行了广泛的研究,但发射器之间直接相互作用在上级式中的精确作用仍然难以捉摸,尤其是在相互作用的复杂性带来重大挑战的多体系统中。在这项研究中,我们研究了偶极bose-Einstein冷凝物(BEC)中18,000个原子之间偶极 - 偶极相互作用的影响。在偶极性BEC中,我们简化了各向异性磁偶极 - 偶极 - 与Bogoliubov转化的复杂作用。我们观察到,各向异性Bogoliubov激发在超级衰减模式下打破了镜像对称性。
Dicke superradiance occurs when two or more emitters cooperatively interact via the electromagnetic field. This collective light scattering process has been extensively studied across various platforms, from atoms to quantum dots and organic molecules. Despite extensive research, the precise role of direct interactions between emitters in superradiance remains elusive, particularly in many-body systems where the complexity of interactions poses significant challenges. In this study, we investigate the effect of dipole-dipole interaction between 18,000 atoms in dipolar Bose-Einstein condensates (BECs) on the superradiance process. In dipolar BECs, we simplify the complex effect of anisotropic magnetic dipole-dipole interaction with Bogoliubov transformation. We observe that anisotropic Bogoliubov excitation breaks the mirror symmetry in decay modes of superradiance.
