Institut Langevin
Institut Langevin is an academic research institute focusing on wave phenomena and imaging, from fundamental to applications. @cnrs.fr @espciparispsl.bsky.social @psl-univ.bsky.social
- 🌊 Chaos as a resource! Near-optimal energy transport can emerge even with limited control. @instlangevin.bsky.social y.social @wesleyanuniversity.bsky.social www.science.org/doi/10.1126/... #WavePhysics #WaveChaos #EnergyTransport
- 🔊 New from @instlangevin.bsky.social: Using time reversal, researchers turn a simple wall into an acoustic router. Sharp focusing, boosted transmission, and multiple sound channels inside the same room, all built from the room’s own reverberation. doi.org/10.1038/s420... #Acoustics #TimeReversal
- 🟠 New study from @instlangevin.bsky.social & @ucauvergne.bsky.social : How shock waves move through granular materials. Three regimes found from gentle impacts to strong shocks, with a surprisingly constant shock-front width (~10 grains). #GranularPhysics #ShockWaves doi.org/10.1016/j.me...
- Can entangled photons beat classical light? 🌀 Researchers from @instlangevin.bsky.social & Hebrew Univ map the limits of wavefront shaping in quantum light—showing when it matches, and when it outperforms, classical optics. #QuantumOptics #Photonics doi.org/10.1063/5.02...
- Light can find rare “open channels” to pass through disorder. Researchers from Institut Langevin and the Hebrew University of Jerusalem reveal how multimode fiber cavities make them accessible. 💡 #Optics #WavePhysics journals.aps.org/prl/abstract...
- Impressive results at NANOP2025 by Lorenzo Soncin: fluorophores mixed with white disordered scattering media exhibit strong spectral changes due to fluorescence photon thermalization with nonzero chemical potential. @instlangevin.bsky.social @espciparispsl.bsky.social @cnrsingenierie.bsky.social
- Outstanding presentation today on the final day of NANOP2025 by our colleague Valentina Krachmalnicoff, showcasing single-molecule sensing of electromagnetic landscapes at the nanometer scale using the smFLIM method. @instlangevin.bsky.social @cnrsingenierie.bsky.social @espciparispsl.bsky.social
- 🔊 Researchers at @instlangevin.bsky.social study how oscillators synchronize by coupling two nonlinear delayed acoustic resonators near a Hopf bifurcation. From frequency locking to desynchronization, they uncover universal patterns of coherence. #Physics #Synchronization doi.org/10.1121/10.0...
- How do you find objects hidden in sand or fog? 🌫️🏝️ A team from @instlangevin.bsky.social & TU Wien just published in Nature Physics a new way to “see” through opaque media using a wave fingerprint matrix — making the invisible visible! 🔍✨ Read more: rdcu.be/eI4Mh #Imaging
- Pedro Mecê wins ERC Starting Grant 2025 for MIRACLE-AD👏 The project uses advanced retinal imaging to detect early signs of Alzheimer’s, mapping neuronal & vascular responses at cellular resolution. 🧠👁 A brilliant blend of physics, optics & clinical medicine! #ERC #RetinalImaging #Neuroscience
- Researchers at Langevin Institute used the “red eye” effect to illuminate the living human eye from behind 👁️✨. This revealed corneal layers, cells, nerve fibers, lens sutures, and guttata in Fuchs’ dystrophy — all in vivo 💡📷. Congrats to the authors 🎉! www.nature.com/articles/s41... #EyeImaging
- 🚀 New theory of wave transport! Researchers at Institut Langevin introduce Radiant Field Theory (RFT), extending the classic radiative transfer equation to capture interference and wavefront shaping. PRL👉 doi.org/10.1103/g3kd...

- Congrats to our colleagues S. Alhaddad, A.C. Boccara, and V. Mazlin, & collaborators at Quinze-Vingts National Ophthalmology Hospital for their paper: Transmission interference microscopy of anterior human eye, published in Nature Communications. doi.org/10.1038/s414... @espciparispsl.bsky.social
- Félicitations à notre cher collègue, le Professeur Arnaud Tourin, nommé Directeur du Département d'Evaluation de la Recherche de l'HCERES ! Il organisera la conduite des évaluations des entités de recherche recevant des financements publics (près de 500 par an). www.aefinfo.fr/depeche/7356...
- 🧠✨ Big step forward in brain imaging! CNRS teams have combined matrix imaging + ultrasound localization microscopy to create super-res 3D images of the brain’s vascular network — artifact-free, beyond MRI & CT. A breakthrough for stroke diagnosis & prevention. 🚀 www.science.org/doi/10.1126/...
- Replaying analog signals backwards with phase preserved is now real. Rare-earth ion-doped crystals + cryo temperatures make real-time wave refocusing possible without digital delays. 🔗 doi.org/10.1364/OL.5... Kudos to Anne Louchet-Chauvet and Thomas Llauze for this work!
- Proud of our colleagues' latest work using guided waves to improve elastography in challenging tissues like tendons. A step forward for more reliable, noninvasive diagnostics! 🔗 Read more in the link doi.org/10.1088/1361... #MedicalImaging #WavePhysics #Elastography
- Félicitations à notre collègue Alex Aubry, qui reçoit le prix J. Jerphagnon 2025 👏 Formé à l’Institut Langevin, il incarne brillamment nos valeurs d’excellence et de recherche transdisciplinaire. Une belle reconnaissance pour un parcours à la croisée de la science et de l’innovation. Bravo Alex !
- Séminaire hors-les-murs de l’Institut Langevin à Saint-Malo 🌊 Deux jours pour penser nos projets autrement, partager nos idées, et prendre un bon bol d’ondes (et d’air marin). Merci à Christelle, Nathalie et Suzanne pour l’organisation parfaite 🙌 #InstitutLangevin #OndesEtImages #SaintMalo
- Proud of our team’s latest work in Science Advances—a major step in high-resolution, noninvasive imaging of neurovascular coupling in the human retina. Congrats to all collaborators! 🔗 www.science.org/doi/10.1126/... @cnrs-paris.bsky.social @espciparispsl.bsky.social @psl-univ.bsky.social
- 👏 Très belle contribution d’Anne Louchet-Chauvet au Congrès Général de la SFP à Troyes ! Elle a présenté ses travaux sur la détection ultra-sensible de déformations dans un cristal dopé aux terres rares. Des avancées prometteuses pour les capteurs de très haute précision. #CGSFP2025 #Physique
- First edition of the Institut Langevin's bike ride. A great day in the sunshine in the Rambouillet forest.

- News from Institut Langevin: temporal disorder doesn't damp waves—it just shifts their frequency. No energy loss. No perturbation theory. Just causality at work. 🔗 doi.org/10.1103/td38... @espciparispsl.bsky.social @cnrsingenierie.bsky.social @cnrs-paris.bsky.social @psl-univ.bsky.social
- Congratulations to the authors: Romain Pierrat, Julia Rocha, @remicarminati.bsky.social
- Researchers from @instlangevin.bsky.social and LPMMC used time-reversed ultrasound to measure diffusion in a dense granular medium. A single sensor refocused waves to their origin, revealing information thought lost. 📄 doi.org/10.1103/47wj...
