6. Classical analogues to chiral light matter interactions in optical cavities: from the Foucault pendulum to the Spyrograph game

Rémi Avriller (IPCMS, CNRS and University of Strasbourg)

Invited Talk

We investigate the mechanism of chiral light-matter interactions for molecular ensembles embedded inside an optical Fabry-Perot cavity. We show how to describe and compute chiroptical properties of such cavities using classical methods based on transfert matrix approaches taking into account the mirror scattering properties. Then we propose and analyse a simplified microscopic model of...

4. Multiqubit state preparation with nanophotonics tools

Invited Talk

In this talk, I will discuss different nanophotonics-based strategies to generate tailored quantum states in emitter ensembles. First, I will explore the creation of highly entangled multiqubit states by inverse engineering of their photonic environment [1]. Next, I will address the preparation of topologically protected excitonic states in emitter chains [2]. Finally, I will briefly examine...

27. Interference-induced cavity resonances and imaginary Rabi splitting

Anael Ben-Asher (Tel Aviv University)

Invited Talk

In nanophotonic environments, light–matter interactions are typically shaped by multiple overlapping electromagnetic modes that interfere with one another, giving rise to sharp spectral features such as Fano profiles. Despite this complexity, polaritons are often described using simplified single-mode cavity QED models.

In this talk, I will show that these interference features can be...

30. Non-equilibrium cavity pumping effects for electronic molecular polaritons

Yassir El Moutaoukal (Norwegian University of Science and Technology – Trondheim, Norway)

Invited Talk

A comprehensive understanding of electron–photon correlation is essential for describing the reshaping of the electronic ground state of molecular systems embedded in quantum electrodynamics (QED) environments. The strong-coupling QED Hartree–Fock (SC-QED-HF) theory addresses these aspects by providing a consistent molecular orbital framework in the strong coupling regime. However, in...
