31. Vibrational dynamics of vibropolaritons formed by organic molecules

Henrike M. Müller-Werkmeister (Institute for Chemistry, University of Potsdam, Potsdam, Germany)

Invited Talk

Vibrational strong coupling, i.e. the formation of polaritons between the vacuum field in Fabry Perot cavities and molecular vibrations, is discussed to allow tuning and steering chemical reactivity. However, mechanistic insights into the vibrational dynamics of the formed vibropolaritons, specifically from experiments, are still limited and not yet available for organic molecules, which are...

Invited Talk

Localized surface plasmons, collective excitations of conduction electrons in nanostructures, are associated to enhanced and spatially localized electromagnetic fields that can strongly couple the plasmonic excitations with the electronic ones of nearby molecules. The resulting hybrid excitations, called plexcitons, share with polaritons the capability of potentially modifying the molecular...

28. Polaritons in complex nanophotonic structures

Prof. Johannes Feist (Universidad Autónoma de Madrid)

Invited Talk

I will discuss the method we have developed over the last years to correctly describe strong light-matter coupling in arbitrary nanophotonic structures. This method obtains a quantum-optics-like description using a few discrete modes while still accounting for the full complexity of light propagation and emission. As a natural consequence, this method yields quantum optical models consisting...

25. Atomistic Simulations of Polaritonic Dynamics in Realistic Optical Cavities

Carlos Bustamante (Max Planck Institute for the Structure and Dynamics of Matter)

Contributed Talk

Polaritonic chemistry involves a vast number of coupled electronic, nuclear, and photonic degrees of freedom, which limits the applicability of fully ab initio approaches. Here, we present a semiclassical simulation framework that self-consistently combines numerical solutions of Maxwell's equations for realistic optical cavities with quantum molecular dynamics at the time-dependent...

26. Combining quantum chemistry methods with macroscopic QED: From polaritonic chemistry to quantum optical device development

Mark Kamper Svendsen (Niels Bohr Institute)

Invited Talk

In this talk, I will present our work on the quantitative description of the cavity for strongly coupled light-matter systems.

I will discuss how Macroscopic Quantum Electrodynamics (MQED) can be combined with high-level quantum chemistry methods for molecular systems. I will also explore how we are using these methods to develop new quantum optomechanical devices. Specifically, I will...
