Abstract

Plasmonic transdimensional materials offer advances such as thickness-controlled light-matter coupling and novel space-time symmetry breaking phenomena to further develop the fields of nanophotonics and optical metasurfaces. Much is unclear though about their optical response and quantum near-field effects. We use quantum electrodynamics and a confinement-induced nonlocal dielectric response model to study the epsilon-near-zero modes of metallic films in the transdimensional regime. New remarkable 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 dipolar spontaneous emission with up to three-orders-of-magnitude increased rates.
