We report a new method to tailor the entire two-dimensional (2D) dispersion relation based
on nonlocal phononic crystals, where beyond-nearest-neighbor (BNN) interactions are used …

This paper explores the emergence of topological interface states in one-dimensional locally
resonant lattices incorporating inerters in both nearest neighbor (NN) and beyond-nearest …

Understanding the phonon behavior in semiconductors from a topological physics
perspective provides more opportunities to uncover extraordinary physics related to phonon …

In the last decade, the study of wave localization and guiding has gained a renewed interest
thanks to the introduction of the concept of topological protection. Originally developed in the …
