Higher-order Skin Effect through a Hermitian-non-Hermitian Correspondence and Its Observation in an Acoustic Kagome Lattice
Jia-Xin Zhong, Pedro Fittipaldi de Castro, Tianhong Lu +8
The non-Hermitian skin effect (NHSE) is a distinctive topological phenomenon observed in nonHermitian systems. Recently, there has been considerable interest in exploring higher-or…
Localized interfacial Phonon Modes at the Electronic Axion Domain Wall
Abhinava Chatterjee, Mourad Oudich, Yun Jing +1
The most salient feature of electronic topological states of matter is the existence of exotic electronic modes localized at the surface or interface of a sample. In this work, in…
Realization of a Z classified chiral-symmetric higher-order topological insulator in a coupling-inversion acoustic crystal
Dongyi Wang, Yuanchen Deng, Mourad Oudich +3
Higher-order topological band theory has transformed the landscape of topological phases in quantum and classical systems. Here, we experimentally demonstrate a two-dimensional (2D…
Observation of degenerate zero-energy topological states at disclinations in an acoustic lattice
Yuanchen Deng, Wladimir A. Benalcazar, Ze-Guo Chen +3
Building upon the bulk-boundary correspondence in topological phases of matter, disclinations have recently been harnessed to trap fractionally quantized density of states (DoS) in…
Magic-angle Bilayer Phononic Graphene
Yuanchen Deng, Mourad Oudich, Nikhil JRK Gerard +3
Thanks to the recent discovery on the magic-angle bilayer graphene, twistronics is quickly becom11 ing a burgeoning field in condensed matter physics. This letter expands the realm…
