Applications of ultrathin plasmonic films, epsilon-near-zero (ENZ) substrates, and 2D magnetic materials to quantum phenomena

In this talk, we will highlight our recent work on ultrathin metal films, epsilon-near-zero (ENZ) substrates, and 2D magnetic materials to engineer quantum phenomena. By exploiting ENZ properties, we manipulate quantum emitters' spontaneous emission rates, create radiative energy band gaps for nanoparticles, and utilize the Casimir effect to generate mechanical motion. Further, we show how ultrathin and 2D magnetic materials could allow for quantum levitation through the generation of nanoscale repulsive forces. Our work reveals the potential for novel device architectures harnessing these effects, offering insights into the intricate interplay between ENZ and 2D magnetic materials with quantum photonic phenomena.
