  • Topological protected acoustic wave propagation has been predicted, but yet awaits for experimental demonstration. Here, Peng et al. report one-way propagation of pseudo-spin-dependent edge states for sound, analogous to Floquet topological insulator in solid state.

  • Phase matching is pivotal for realizing complete energy transfer for classical waves. Here, authors propose temporal quasi-phase matching method and realize robust and complete energy transfer between arbitrarily detuned acoustic cavities by combing the concept of stimulated Raman adiabatic passage.

  • Here, the authors propose an ultrasonic meta-lens for generating super-oscillation wave packets with different spatial momenta and then superimposing them to a diffraction-limit-broken spot. They experimentally verify super-resolution ultrasound imaging of subwavelength objects.

  • In this type of thermal cloak, when a fluid circulates around the object of interest, the temperature perturbation is minimized as the effective thermal conductivity of the fluid becomes very high due to convective effects.

  • The researchers report a class of silica-nanoparticle-decorated bacteria-cellulose ultrasonic metasurfaces that feature excellent stability in water and mechanical processability. They demonstrate it as holographic meta-lens and 3D imaging meta-lens.

  • The use of time modulation to break reciprocity is well understood for light, sound or charge diffusion, but it’s unclear whether it can work for thermal diffusion. Here, the authors answer in the negative by analysing diffusive processes under time modulation, and giving numerical and experimental evidence.

  • Non-Hermitian systems can house a range of unusual physical phenomena such as the skin-effect which has been typically observed in optical lattices and electrical circuits. Here, the authors show the non-Hermitian skin effect in thermal transport, demonstrating that the topologically protected heat flow can be realized by using thermal metamaterials.
