Requisites on viscoelasticity for exceptional points in passive elastodynamic metamaterials
Abhishek Gupta, Ramathasan Thevamaran
The recent progress of non-Hermitian physics and the notion of exceptional point (EP) degeneracies in elastodynamics has led to the development of novel metamaterials for the contr…
Enhanced Signal-to-Noise Performance of EP-based Electromechanical Accelerometers
Rodion Kononchuk, Jizhe Cai, Fred Ellis +2
Exceptional points (EP) are non-Hermitian spectral degeneracies where both eigenvalues and their corresponding eigenvectors coalesce. Recently, EPs have attracted a lot of attentio…
Origins of size effects in initially dislocation-free single-crystal metallic micro- and nanocubes
Claire Griesbach, Seog-Jin Jeon, David Funes Rojas +6
We report phenomenal yield strengths, up to one fourth of the theoretical strength of silver, recorded in microcompression testing of initially dislocation free silver micro and na…
Environmentally-induced exceptional points in elastodynamics
V. Dominguez-Rocha, Ramathasan Thevamaran, F. M. Ellis +1
We study the nature of an environment-induced exceptional point in a non-Hermitian pair of coupled mechanical oscillators. The mechanical oscillators are a pair of pillars carved o…
Asymmetric Acoustic Energy Transport in Non-Hermitian Metamaterials
Ramathasan Thevamaran, Richard Massey Branscomb, Eleana Makri +4
The ability to control and direct acoustic energy is essential for many engineering applications such as vibration and noise control, invisibility cloaking, acoustic sensing, energ…
