We develop a framework that provides a few-mode master equation description of the interaction between a single quantum emitter and an arbitrary electromagnetic environment. The field quantization requires only the fitting of the spectral density, obtained through classical electromagnetic simulations, to a model system involving a small number of lossy and interacting modes. We illustrate the power and validity of our approach by describing the population and electric field spatial dynamics in…

Accurate Truncations of Chain Mapping Models for Open Quantum Systems
It is demonstrated that extending the chain mapping to allow next-nearest neighbor coupling permits the reproduction of an arbitrary environment, and adding longer-range interactions does not further increase the effective number of degrees of freedom in the environment.
Few-mode Field Quantization for Multiple Emitters
The control of the interaction between several quantum emitters using nanophotonic structures holds great promise for quantum technology applications. However, the theoretical description of such

In the last decade, much theoretical research has focused on studying the strong coupling between organic molecules (or quantum emitters, in general) and light modes. The description and prediction

Distortion of the local density of states in a plasmonic cavity by a quantum emitter
We investigate how the local density of states in a plasmonic cavity changes due to the presence of a distorting quantum emitter. To this end, we use first-order scattering theory involving

Molecular photodissociation enabled by ultrafast plasmon decay.
The concept of enabling photodissociation of a normally photostable molecule through coupling to a nanoparticle plasmon is demonstrated using numerical simulations of the Lindblad master equation for the hydrogen molecule in the vicinity of an aluminum nanoparticle and the photodism efficiency as a function of various system parameters is explored.


Cumulant expansion for the treatment of light-matter interactions in arbitrary material structures.
This work investigates a compromise where the quantum character of light is taken into account at modest computational cost and employs the cumulant, or cluster, expansion method to the Heisenberg equations of motion up to first, second, and third order.

The dielectric constant of the medium is explicitly derived and is shown to satisfy the Kramers-Kronig relations and the exact eigenoperators for the coupled system are calculated.
