Chen Ying, a teacher of Huaqiao University, published important results in the top international physics journal

Recently, Chen Ying, a teacher at the Department of Physics at the School of Information of OCT University, cooperated with Professor Chen Huanyang of Xiamen University and Professor Jiang Jianhua from Suzhou University to publish the "Observation Of Topology P-ORBITAL DISCLINATION States in Non-EuClidean Acoustic Metamaterial ", for the first time, observed the Par orbit Turdish errors in the non-European acoustic super material structure to explore the topological characteristics of more nanometer materials on the curved surface. New ideas.

This paper mainly studies the topological situation caused by the error defects in the graphene pattern of acoustic graphene, which is different from the rotation errors in the plane (European) geometry of previous experimental work. 2π/3 Perfect Crystal Silee Corresponding Conechical or Bilateral Curly -shaped curved errors, consider the influence of local curvature on the defect, and use three -dimensional printing technology to build a non -European geometric shape. Acoustic topology crystals. Through the combination of theoretical calculation, numerical simulation, and experimental representation, it observed the local area of ​​P orbit distribution in the topology gap, and these attitudes will show the distribution characteristics of surprising symmetry and partial symmetry.

The paper explores the interesting interaction between non -European geometric shapes caused by topology and topological defects, and introduces P orbit physics into the study of rotation, showing a rich rail structure and strong locality. Because lattice defects are widely existed in nano structures, such as graphene, boron nitride, transition metal sulfide and other two -dimensional materials or other nano -materials, the topology characteristics of many electronic or sounds still need to be explored. Using acoustic ratio, this study can stimulate more research on top topology in the non -European super material structure in the future.

It is understood that the paper takes Chen Ying as the first author and OCT University as the first completion unit. Professor Chen Huanyang of Xiamen University, Professor Jiang Jianhua of Suzhou University, and Chen Ying, a school teacher Chen Ying, are the common communication authors of the dissertation. The research has received strong support from the National Natural Science Foundation of China, special funds for basic scientific research business fees for the central university, and the funds for the start of funds for Huaqiao University. It is worth mentioning that Chen Ying is an excellent doctor introduced in 2020 and obtained the National Natural Science Foundation of China Youth Science Fund project in 2021, which fully reflects the effect of the school's talent policy.
