Classical plasmonics fails at nanoscale separations. This study unifies mesoscopic electrodynamics to accurately model quantum effects, improving predictions for plasmon-emitter interactions in nanophotonics.

Area of Science:

Nanophotonics and Plasmonics
Quantum Electrodynamics at the Nanoscale

Background:

Plasmon-emitter interactions are crucial in nanoplasmonics, typically peaking at short distances.
Classical theories falter below 10-20 nm due to neglecting quantum effects like nonlocality and Landau damping.

Purpose of the Study:

To develop a unified theoretical framework for mesoscopic electrodynamics.
To accurately incorporate quantum effects into plasmon-emitter interaction models.
To provide a rigorous platform for studying nanoscale plasmon phenomena.

Main Methods:

Incorporation of Feibelman $\alpha$-parameters into a mesoscopic electrodynamics treatment.
Inclusion of nonclassical resonance shifts and surface-enabled Landau damping.
Theoretical analysis of diverse plasmon-emitter interactions.
