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!
