Professor
Olivier Richoux is a Professor at the Institute of Acoustics, Department of Acoustics, University of Le Mans. His research spans topological acoustics, wave propagation in complex media, and acoustic metamaterials, with significant contributions to understanding nonlinear wave phenomena and topological edge states in engineered structures. Richoux's research interests focus on topological acoustics and nonlinear wave dynamics in structured media. His work explores how topological principles can create robust acoustic waveguides resistant to defects, and investigates soliton formation in periodic systems. Key areas include Su-Schrieffer-Heeger analogues in acoustic lattices, coherent perfect absorption in asymmetric networks, and energy spreading in disordered systems. His experimental-theoretical approach bridges fundamental physics with practical applications in sound control. Analysis of his recent publications (2021-2025) reveals a strong trend toward topological wave engineering in acoustic systems, particularly using Su-Schrieffer-Heeger models to create defect-immune wave paths. His work increasingly integrates nonlinear dynamics with topological concepts, examining soliton propagation and energy localization in disordered media. The research demonstrates consistent focus on experimental validation through acoustic waveguide networks and metamaterial implementations. Richoux actively collaborates within the Institute of Acoustics research ecosystem, particularly with teams working on ultrasonics, metamaterials, and nonlinear acoustics. His work frequently appears in high-impact journals including Physical Review B, Physical Review Applied, and Journal of the Acoustical Society of America, demonstrating strong integration within the international acoustics community. His laboratory work centers on acoustic waveguide networks and metamaterial testbeds for studying topological phenomena. The research group utilizes advanced measurement techniques including laser ultrasonics and optical methods for acoustic characterization, with facilities supporting both theoretical modeling and experimental validation of complex wave phenomena.
