We extend the model of exciton-plasmon materials to include a ro-vibrational structure of molecules using wave-packet propagations on electronic potential energy surfaces. The new model replaces conventional two-level emitters with more complex molecules allowing to examine the influence of alignment and vibrational dynamics on strong coupling with surface plasmon-polaritons. We apply the model to a hybrid system comprising a thin layer of molecules placed on top of a periodic array of slits…

The consequences of a more detailed description of the molecular environment in terms of its quantum density matrix makes it possible to account for characteristics that cannot be described by the dielectric response model: the effects of dephasing on the molecular response on one hand, and nonlinear response on the other.
Plasmon enhanced second harmonic generation by periodic arrays of triangular nanoholes coupled to quantum emitters.
It is demonstrated that the energy conversion efficiency in the second harmonic process is the highest when the system is pumped at the localized surface plasmon resonance.
Effects of exciton-plasmon strong coupling on third harmonic generation of WS2 monolayer at periodic plasmonic interfaces
We study theoretically optical response of WS2 monolayer located near periodic metal nanostructured arrays in two and three dimensions. The emphasis of simulations is on the strong coupling regime of

We developed a model to account for electron-vibrational effects on absorption, luminescence of molecular aggregates, and exciton-polaritons in nanofibers. The model generalizes the mean-field
Extracting spectroscopic molecular parameters from short pulse photo-electron angular distributions.
This work investigates the femtosecond and picosecond energy- and angle-resolved photoelectron spectra of the E(Σg+1) electronic state of Li2 and derives a simple analytical formula which can be used to extract the asymptotic CW asymmetry parameters of individual transitions from measurements performed with ultra-short pulses.
Single-particle model of a strongly driven, dense, nanoscale quantum ensemble
We study the effects of interatomic interactions on the quantum dynamics of a dense, nanoscale, atomic ensemble driven by a strong electromagnetic field. We use a self-consistent, mean-field
Quantum Control of Open Systems and Dense Atomic Ensembles
Controlling the dynamics of open quantum systems; i.e. quantum systems that decohere because of interactions with the environment, is an active area of research with many applications in quantum
