We experimentally achieve wave mode conversion and rainbow trapping in an elastic waveguide loaded with array of resonators. Rainbow is a phenomenon that induces confinement as result spatial variation the velocity, here promoted by gently varying length consecutive By breaking geometrical symmetry waveguide, we combine speed reduction reflection mechanism mode-converts flexural waves impinging...

In the context of quantum technologies over continuous variables, Gaussian states and operations are typically regarded as freely available, they relatively easily accessible experimentally. contrast, generation non-Gaussian states, well implementation operations, pose significant challenges. This divide has motivated introduction resource theories non-Gaussianity. As for any theory, it is prac...

The partial or complete confinement of waves in an open system is omnipresent nature and wave-based materials technology. Here, we theoretically analyze experimentally observe the formation a trapped mode with perfect conversion (TMPC) between flexural longitudinal waves, by achieving quasi-bound state continuum (BIC) elastic wave system. latter allows quasi-BIC semi-infinite background plate w...
