我们使用量子电动力学和基于Keldysh-Rytova电子相互作用势的约束诱导非局域介电响应模型来研究金属薄膜在跨维区域的ε近零模。新的奇特的效果，如等离子体振子模式简并提升和偶极发射耦合到分裂ε近零模式，导致厚度控制的自发衰减高达三个数量级的增加率。
We use quantum electrodynamics and the confinement-induced nonlocal dielectric response model based on the Keldysh-Rytova electron interaction potential to study the epsilon-near-zero modes of metallic films in the transdimensional regime. New peculiar effects are revealed such as the plasmon mode degeneracy lifting and the dipole emitter coupling to the split epsilon-near-zero modes, leading to thickness-controlled spontaneous decay with up to three-orders-of-magnitude increased rates.
