Polarization-dependent and Valley-protected Lamb Waves in Asymmetric Pillared Phononic Crystals
Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani +1
We present the realization of the topological valley-protected zero-order antisymmetric (A0) or symmetric (S0) and zero-order shear-horizontal (SH0) Lamb waves at different domain…
Valley and pseudospin-valley topologically protected edge states in symmetric pillared phononic crystals
Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani +1
We present a symmetric double-sided pillared phononic crystals (PPnCs) that can emulate both quantum spin Hall effect (QSHE) and quantum valley Hall effect (QVHE) by solely imposin…
Exceptional point enhances sensitivity of optomechanical mass sensors
P. Djorwé, Y. Pennec, B. Djafari-Rouhani
We propose an efficient optomechanical mass sensor operating at exceptional points (EPs), non-hermitian degeneracies where eigenvalues of a system and their corresponding eigenvect…
