Synthetic Kramers pair in phononic elastic plates and helical edge states on a dislocation interface
Ting-Wei Liu, Fabio Semperlotti
In conventional theories, topological band properties are intrinsic characteristics of the bulk material and do not depend on the choice of the reference frame. In this scenario, t…
Weyl points and topological surface states in a three-dimensional elastic lattice
Sai Sanjit Ganti, Ting-Wei Liu, Fabio Semperlotti
Following the realization of Weyl semimetals in quantum electronic materials, classical wave analogues of Weyl materials have also been theorized and experimentally demonstrated in…
Non-conventional topological band properties and gapless helical edge states in elastic phononic waveguides with Kekulé distortion
Ting-Wei Liu, Fabio Semperlotti
This study investigates the topological behavior of a continuous elastic phononic structure characterized by a 3-term Kekulé distortion. The elastic waveguide consists of a hexagon…
Experimental evidence of robust acoustic valley Hall edge states in a non-resonant topological elastic waveguide
Ting-Wei Liu, Fabio Semperlotti
This paper presents experimental evidence of the existence of acoustic valley Hall (AVHE) edge states in topological elastic waveguides. The fundamental lattice is assembled based…
Tunable Acoustic Valley-Hall Edge States in Reconfigurable Phononic Elastic Waveguides
Ting-Wei Liu, Fabio Semperlotti
This study investigates the occurrence of acoustic topological edge states in a 2D phononic elastic waveguide due to a phenomenon that is the acoustic analogue of the quantum valle…
