Observation of multiple rotons and multidirectional roton-like dispersion relations in acoustic metamaterials
Roton dispersion relations were firstly predicted by Landau and have been extensively explored in correlated quantum systems at low temperatures. Recently, the roton-like dispersion relations were theoretically extended to classical acoustics, which, however, have remained elusive in reality. Here,...
