I am humbled to share the 2023 Brillouin Medal with Professor Tianli Feng for our work on four-phonon scattering. Many thanks to the International Phononics Society for the incredible recognition. I am grateful to all my mentors, students, collaborators and supporters for making it happen. Many thanks to the experimentalists who confirmed our theory later. Special thanks to Physical Review B, which was willing to publish our papers when our theory was considered too risky and of no broad interest at the time (understandable as indeed no experimental confirmation was in place and nobody else was publishing on this topic).

“At the time (2016-2017), their (four-phonon scattering) theory and predictions came as a surprise to the community, and there was a lot of skepticism about the work. However, it was later confirmed by several important experiments, which facilitated the acceptance of their theory. The 2017 publication has now received nearly 400 citations, becoming a top 1% cited paper in physics and named a Highly Cited Paper by Clarivate Web of Science. The four-phonon scattering theory was included in the 2nd edition of a widely used graduate textbook, Nano/Microscale Heat Transfer, published by Springer in 2020.”
“People refer to our 2017 paper much more, as it studied boron arsenide, now a star material,” said Ruan. “However, in our minds the 2016 work is more important, because it took the first step to tackle four-phonon scattering and laid down the formulation and computational method. It was the longest and most challenging step in our journey.”
Xiulin Ruan has received the 2023 Brillouin Medal, given to honor a specific seminal contribution in the field of phononics. This highlights Ruan's groundbreaking work on four-phonon scattering: https://lnkd.in/gTrH7NMP
