Vincent Pagneux from Laboratoire d'Acoustique at Université of Le Mans starts the afternoon session with a seminar: From networks of acoustic waveguides to lattice models: effects of symmetry and topology. Music to our ears! @iescargese.bsky.social

We finish the morning session with another contributed talk by Alejandro Caballero @ifimacuam.bsky.social from talking about interface states in space-time photonic crystals: topological origin, propagation and amplification. Topological waves living life on the edge! @iescargese.bsky.social

Now a contributed talk by Rohin E. McIntosh from @yale.edu about multitarget spatiotemporal power deposition inside diffusive media. From diffusive to decisive media!

We start our last day of Wave in Complex Media 2026 @iescargese.bsky.social with Fabrice Mortessagne from @univcotedazur.bsky.social teaching us about the quantum Hall effects and microwaves: an incursion into wave topology. Hall of fame for microwaves!

We finish the day with Hui Cao from @yale.edu presenting her work on light control in complex media - without time reversal. Light bends to her will! @iescargese.bsky.social

We welcome now Angélique Campaniello (@instlangevin.bsky.social @espciparispsl.bsky.social) for a contributed talk about experimentally controlling scattering of water waves in correlated disorder. Making a splash with correlated disorder! @iescargese.bsky.social

We start this afternoon with a seminar by Humeyra Caglayan @metaplasmonics.bsky.social from @tue.nl on metaoptics for optical computing toward intelligent visual perception. Eye see what you did there! @iescargese.bsky.social

Last talk of this morning session at @iescargese.bsky.social with a seminar by Ulf Leonhardt from the Weissman Institute of Science about wave noise in time-dependent media and cosmic expansion. Making waves across space and time!

Group picture of the Waves in Complex Media 2026 @iescargese.bsky.social

We continue with a contributed talk by Gabriel Hayoun about the localization-landscape generalized Mott-Berezinskii formula. Electrons playing hide and seek in a disordered landscape! @iescargese.bsky.social

We start the 4th day of WCM 2026 at @iescargese.bsky.social with Valentina Krachmalnicoff and Rémi Carminati @espciparispsl.bsky.social giving a lecture on the study of Light–Matter Interaction: Theoretical Framework and Experimental Approaches. DOS and don'ts of light–matter interaction!

Nous avons le plaisir d'écouter Hugo Defienne pour une conférence grand public @iescargese.bsky.social devant une audience venue en nombre l'écouter nous parler des photons dans sa présentation didactique et expérimentale intitulée : « À la poursuite du photon : filmer la lumière grain par grain ».

Last session of the day with Lyuba Amitonova @vuamsterdam.bsky.social presenting her work on computational imaging through multimode fibers. Threading the needle of imaging! @iescargese.bsky.social

We continue with a second lecture by Tsampikos Kottos from Wesleyan University on transport modes and information in complex media. It's all about the right mode-ivation! @iescargese.bsky.social

And we start the day @iescargese.bsky.social with some math with Pr. Josselin Garnier @polytechniqueparis.bsky.social and a lecture on AI and data driven methods for quantitative imaging. Seeing through tissues, bit by bit!

Beautiful science and cheesy puns, we are back to cover our Waves in Complex Media @iescargese.bsky.social www.institut-langevin.espci.fr/cargese_2026

For the final talk of the day, we have Hugo Defienne @insp-lab.bsky.social giving a seminar on entanglement-enabled imaging through complex media. When two photons are better than one! @iescargese.bsky.social #wavefrontshaping
