Anomalous topological edge states in non-Hermitian piezophononic media
Penglin Gao, Morten Willatzen, Johan Christensen
The bulk-boundary or bulk-edge correspondence is a principle relating surface confined states to the topological classification of the bulk. By combining non-Hermitian ingredients…
Topological sound pumping of zero-dimensional bound states
Penglin Gao, Johan Christensen
Topological phases have spurred unprecedented abilities for sound, light and matter engineering and recent progress has shown how waves not only confine at the interfaces between t…
Majorana-like zero modes in Kekulé distorted sonic lattices
Penglin Gao, Daniel Torrent, Francisco Cevera +3
Topological phases have recently been realised in bosonic systems. The associated boundary modes between regions of distinct topology have been used to demonstrate robust waveguidi…
Scattering of flexural waves from an -beam resonator in a thin plate
Alfonso Climente, Penglin Gao, Linzhi Wu +1
The impedance matrix method is applied to study the scattering of flexural waves propagating in an infinite thin plate containing an -beam resonator. The resonator consists of a…
