Our paper on Few-mode field quantization for multiple emitters has been published in Nanophotonics!

Controlling the interaction between quantum emitters using nanophotonic structures holds great promise for quantum technology applications. However, its theoretical description for complex nanostructures is highly demanding as the electromagnetic modes form a high-dimensional continuum.

In this work, we introduce an approach that permits a quantized description of the full EM field through a small number of discrete modes. This extends our previous work to the case of an arbitrary number of emitters, without any restrictions on the emitter level structure or dipole operators.

The low computational demand of this method makes it suitable for studying dynamics for a wide range of parameters. We illustrate the power of our approach for a system of three emitters placed within a hybrid metallodielectric photonic structure and show that excitation transfer is highly sensitive to the properties of the hybrid photonic-plasmonic modes.

This method provides a practical tool for studying complex light-matter interactions in realistic nanophotonic systems.

This was the last paper based on the thesis work of Mónica Sánchez Barquilla, and done in collaboration with Francisco J. García-Vidal and Antonio I. Fernández-Domínguez.
