Biexcitons in Ruddlesden-Popper Metal Halides Probed by Nonlinear Coherent Spectroscopy

📄New preprint now on arXiv!
We are excited to share that our latest collaborative work, “Biexcitons in Ruddlesden-Popper Metal Halides Probed by Nonlinear Coherent Spectroscopy,” led by Katherine Koch and Ajay Ram Srimath Kandada, has just been uploaded to the arXiv.

In this mini-review, we explore how biexcitons — bound states of two electrons and two holes — can be unambiguously identified and characterized in Ruddlesden-Popper metal halide materials using advanced nonlinear coherent spectroscopies. This work highlights the power of multidimensional optical techniques to understand many-body interactions in quantum-confined semiconductors and strengthens the foundations for future quantum materials research.

Thank you to all co-authors and colleagues who contributed to all of our previous research papers that we review in this work. I look forward to feedback from the community and to the next steps in this exciting direction!

Resolving exciton and polariton multiparticle correlations in an optical microcavity in the strong-coupling regime

We are proud to report that our article titled “Resolving exciton and polariton multi-particle correlations in an optical microcavity in the strong coupling regime” led by Victoria Quirós-Cordero and Esteban Rojas Gatjens has been selected as an Editor’s Suggestion in Physical Review B.

Teaser text: “Here the authors use advanced nonlinear spectroscopy to directly observe how excitons and polaritons interact in a strongly coupled semiconductor microcavity. Their measurements reveal ultrafast energy flow into polariton states and uncover clear signatures of multi-particle Coulomb interactions that link reservoir and polariton modes. These previously hidden correlation pathways shape polariton behavior far beyond mean-field expectations, offering fresh insight into the fundamental processes that enable polariton condensation and other collective quantum phenomena”.
