Our news

  • Mr. Tanguy Delaporte, a student from ESPCI, is spending three months with us! (May 2023)

  • We show how to improve the quality of focal spots when focusing through random media using spatial wave modulators. There are some interesting findings that surprise us. Find out in our paper on PR Applied. (Mar. 2023)


  • Incoming group member: Xiaoming Wang from South China Normal University. (Jan. 2023) 


  • In our new paper in PRL, we use non-Hermitian skin effect to turn a BIC (bound state in a continuum) "upside down." (Dec. 2022)

  • Dr. Dongyi Wang has joined our group from Fudan University. (Sep. 2022) 

  • ​New paper in Nature! We show how topological modes can be entirely delocalized from boundaries with the help of non-Hermitian skin effects. (Aug. 2022)


  • In a new paper in PR Applied, we demonstrate the possibility of controlling disordered transient sound using reconfigurable metasurfaces. Congratulations to Qiyuan, the youngest of our group members, on his first-ever paper! And big thanks to our collaborator Dr. Philipp del Hougne from Univ. Rennes! (Apr. 2022)

  • Our first attempt at photonics ends up in Nature Photonics! Grateful to Prof. Xu-Lin Zhang and Prof. Hong-Bo Sun (and other collaborators) of Jilin University for the amazing on-chip non-Abelian photonic braiding experiment! (Mar. 2022)

  • ​By taking advantage of non-Hermitian topology, we demonstrate the compete set of permutations in a non-Abelian D3 group. Read about it in our new paper on National Science Review. (Jan. 2022)

  • We report the successful realization of non-Abelian braiding and quantum-logic operations in acoustics in a new paper on Nature Physics! And it comes with a nice piece of commentary! (Dec. 2021)

  • Congrats to Dr. Wei Wang on his first PRL, reporting a new type of 3D hybrid topological phase in synthetic-reciprocal space. (Nov. 2021)

  • A new member joins our team: Dr. Zhen Li from Xi'an Jiao Tong University! (Nov. 2021)

  • In this collaborative work with Dr. Shubo Wang, we show how structured sound can mimic elastic waves by displaying not only shear response but also "micro-rotation" degrees of freedom. Kudos to Guanqing for performing the experiments! Read our paper on Nature Communications! (Oct. 2021)

  • It is well-known that topological edge states can guide waves to propagate alone edges. In our new paper in
    PR Applied, we show that they can also guide waves in the direction perpendicular to the edge, and even achieve negative refraction! (Oct. 2021)

  • Do you know that the energy carried by a wave emitted by a small source can "hesitate" about leaving the source? Read our new paper in PR Applied to see how and why! (Jul. 2021)
