Majorana-like Zero Modes in Kekulé Distorted Sonic Lattices
American Physical Society (2019)Topological phases have recently been realized in bosonic systems. The associated boundary modes between regions of distinct topology have been used to demonstrate robust waveguiding, protected from defects by the topology ... -
Mechanical Analogue of a Majorana Bound State
Wiley (2019)The discovery of topologically nontrivial electronic systems has opened a new age in condensed matter research. From topological insulators to topological superconductors and Weyl semimetals, it is now understood that some ...

Multiple scattering theory of non-Hermitian sonic second-order topological insulators
(2019-10-25)Topological phases of sound enable unconventional confinement of acoustic energy at the corners in higher-order topological insulators. These unique states which go beyond the conventional bulk-boundary correspondence have ...

Non-locality of the Willis coupling in fluid laminates
Elsevier B.V. (2022-02-04)The closed form expressions of the effective properties in periodic fluid laminates are derived thanks to the Padé approximation of the transfer matrix. A second-order Taylor expansion of the transfer matrix elements ... -
Nonreciprocal and even Willis couplings in periodic thermoacoustic amplifiers
American Physical Society (2021-11-10)hermoacoustic amplifiers are analyzed in the framework of nonreciprocal Willis coupling. The closed form expressions of the effective properties are derived, showing that an applied temperature gradient causes the appearance ...

Ultrathin Acoustic Parity-Time Symmetric Metasurface Cloak
American Association for the Advancement of Science (2019)Invisibility or unhearability cloaks have beenmade possible by using metamaterials enabling light or sound to flow around obstacle without the trace of reflections or shadows. Metamaterials are known for being flexible ...
