Invited Talk

Theoretically explaining experimental observations of cavity-modified physics and chemistry remains to be a major challenge, in particular for a large number of coupled molecules. Here I discuss our bottom-up approach with minimal quantum optics many-body models, which include electronic, photonic, and motional degrees of freedom in their simplest form.

This talk will review how dark...

Invited Talk

The exchange of energy between electronic and nuclear motion is the origin of non-adiabaticity and plays an important role in many molecular phenomena and pro-cesses. Conical intersections (CIs) of different electronic potential energy surfaces lead to the most singular non-adiabaticity and have been intensely investigated. The
coupling of light and matter induces conical intersections which...

12. Is polaritonic chemistry a manifestation of a spin glass?

Invited Talk

We demonstrate that the collective vibrational strong coupling of molecules in thermal equilibrium can give rise to significant local electronic polarizations in the thermodynamic limit. The discovered cavity-induced polarization pattern possesses a zero net polarization, which resembles a continuous form of a spin glass (or better polarization glass). Eventually, theoretical connections to...

19. Cavity-Born-Oppenheimer Hartree-Fock: Vibronic-Strong-Coupling beyond a single molecule

Thomas Schnappinger (Stockholm University)

Invited Talk

When molecules are placed in a non-classical photonic environment present in optical or nanoplasmonic cavities, it is possible to form strong light-matter-coupled hybrid states called polaritons. Recent experiments show that this strong coupling between light and matter is capable of modifying chemical and physical properties and offer a possible novel approach to control chemical reactions....
