Great couple of weeks at IFUNAM hosting Frank Vewinger, Georg Bruun, Edgar Cerda! Lots of physics, seminars, discussions with our students, new ideas and collaborations — and, of course, some good food :) Thanks for visiting us and see you again soon in Mexico! 🇲🇽.

Very happy to see our collaboration with the Heidelberg- Bonn group published today in Science Advances! We experimentally demonstrate critical scaling in an essentially ideal Bose gas, providing evidence for the distinct Bose gas universality class. science.org/doi/epdf/10.1126…

Excited to share that our manuscript, "Scalable dip-coated Bragg mirrors for strong light–matter coupling with 2D perovskites", has been published in Materials Advances! We demonstrate scalable Bragg mirrors for polaritons at room temperature. Nice collaboration @unsamoficial

Happy to see our cover art appearing in @ACSPhotonics. You can read our work on Room-Temperature Polariton Condensate Confined in a Self-Assembled Perovskite Microcavity pubs.acs.org/doi/10.1021/acs… Is Open Access =) @IF_UNAM

Our room-temperature polariton condensate is finally out! We demonstrate a condensate of light and matter in self-assembled perovskite microcavities, including observation of macroscopic coherence and vortices A huge team effort from @QuantumFluidsof . pubs.acs.org/doi/10.1021/acs…

Polariton condensates in coupled cavities form intercavity phonon-polaritons, hybrid light-matter collective excitations with spatially separated components. Iliana’s first paper is now on arXiv: arxiv.org/abs/2603.23479

The conference Etic-Tlahuilli gathered an outstanding list of panelists in quantum many-body physics of light and matter. We are very happy to see a growing community . The Communication office of our Institute wrote a very nice article on our event fisica.unam.mx/organizacion/…

Intercavity polaritons: light–matter quasiparticles made of photons and excitons that spatially segregate but are strongly coupled. Led by our outstanding PhD student: Rodrigo Sánchez, now in @PhysRevApplied unveils a mechanism protecting these states. journals.aps.org/prapplied/a…

Registration is Now Open! We are excited to announce the Second Edition of Etic-Tlahuilli: Polariton Meeting, taking place in Mexico City this October 27–30, 2025. - Quantum Fluids of Light - Ultracold Atomic Gases - Quantum Optics docs.google.com/forms/d/e/1F…

Our manuscript on room-temperature polariton condensates, “Macroscopic coherence and vorticity,” is finally out on arXiv arxiv.org/abs/2508.13042
