Regulation of high-frequency vibrations via phononic crystal structure with zero Poisson’s ratio

open access: yesAIP Advances
Vibration affects the service life of engineering structures and the working accuracy of instruments, causing engineering accidents such as structural collapse and equipment explosion. Phononic crystals can effectively suppress the propagation of elastic

One-Dimensional Mass-Spring Chains Supporting Elastic Waves with Non-Conventional Topology

open access: yesCrystals, 2016
There are two classes of phononic structures that can support elastic waves with non-conventional topology, namely intrinsic and extrinsic systems. The non-conventional topology of elastic wave results from breaking time reversal symmetry (T-symmetry) of

Phonons in electron crystals with Berry curvature

open access: yesProceedings of the National Academy of Sciences
Recent advances in 2D materials featuring nonzero Berry curvature have inspired extensions of the Wigner crystallization paradigm. This paper derives a low-energy effective theory for such quantum crystals, including the anomalous Hall crystal (AHC) with nonzero Chern number.
