Observation of roton-like dispersion relations in acoustic metamaterials
Zhenxiao Zhu, Zhen Gao, Gui-Geng Liu +8
Roton dispersion relations, displaying a pronounced "roton" minimum at finite momentum, were firstly predicted by Landau and have been extensively explored in correlated quantum sy…

Acoustic non-Hermitian skin effect from twisted winding topology
Li Zhang, Yihao Yang, Yong Ge +11
The recently discovered non-Hermitian skin effect (NHSE) manifests the breakdown of current classification of topological phases in energy-nonconservative systems, and necessitates…
