2. New Experimental Platforms for Polariton Reaction Dynamics

Marissa Weichman (Princeton University)

Invited Talk

Polaritons are hybrid light-matter states with unusual properties that arise from strong interactions between a molecular ensemble and the confined electromagnetic field of an optical cavity. Cavity-coupled molecules can demonstrate energetics, reactivity, and photophysics dramatically distinct from their free-space counterparts, but the mechanisms and scope of these phenomena remain open...

7. Simulating chemical dynamics under vibrational strong coupling, what to take from it, and where to go next

Christian Schäfer (Chalmers)

Invited Talk

Polaritonics has demonstrated remarkable capabilities, including the non-intrusive control over chemical reactivity and solvation dynamics.
Our understanding of the underlying microscopic mechanism is limited, at best, largely caused by a lack of predictive theory that is able to connect to experimental observables. Here, I will present our recent attempts in overcoming this challenge using...

8. Simulating (ro)vibrational polaritons: (1) an efficient and flexible approach, (2) the consequences of the Pauli principle

Tamás Szidarovszky (Eötvös Loránd University)

Short talk

In this poster I present two topics:

(1) A theoretical framework is presented for the computation of rovibrational polaritonic states of a molecule in a lossless infrared (IR) microcavity.
In the proposed approach the quantum treatment of the rotational and vibrational motion of the molecule can be formulated using arbitrary approximations. The cavity-induced changes in electronic...

4. Targeting the dark states in strongly coupled systems

Karl Börjesson (the University of Gothenburg)

Invited Talk

Strong light-matter coupling generates hybrid states that inherit properties of both light and matter, effectively allowing the modification of the molecular potential energy landscape. This phenomenon opens a plethora of options for manipulating the properties of molecules, with a broad range of applications in physics, chemistry, and materials science. In this presentation, I will focus on...

23. Ultra-fast photochemistry under strong light-matter coupling

Prof. Jussi Toppari (Nanoscience Center & Department of Physics, University of Jyväskylä)

13/08/2024, 11:30

Invited Talk

Strong coupling between photoactive molecules and confined light modes results in the formation of hybrid light-matter states, polaritons, with energies above and below the original states of the molecule and cavity. This has been shown to alter the photochemistry of the molecules [1], but the details of this effect remains largely unknown. In a typical Fabry-Pérot cavity strong coupling is...

17. Excitation energy transfer in disordered organic polaritons: Does it matter if they are dark or bright?

Ilia Sokolovskii (University of Jyväskylä)

Short talk

Placing organic molecules in an optical cavity holds a great promise for the improvement of excitation energy transfer in such molecules due to the hybrid nature of the emerging light-matter quasiparticles, called polaritons. Recently, it was envisaged that a large static disorder of molecular excitation energies could benefit the transport of polaritons even further, leading to the so-called...
