Coherent Surface Acoustic Wave Reflection via Microfluidic Phononic Crystal Devices [PDF]
The integration of surface acoustic wave (SAW) technology with Lab-on-a-Chip (LOC) devices has enabled powerful acoustic mechanisms for cell sorting, cell deflection, and other types of manipulation of biological specimen.

One-step polymeric phononic crystal manufacture.
A versatile system to construct bulk polymeric phononic crystals by using acoustic waves is described. In order to fabricate this material, a customised cavity device fitted with a ∼2 MHz acoustic transducer and an acoustic reflector is employed for the ...

Phonons in electron crystals with Berry curvature
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.
