Classification of rotational zero modes in 2D micropolar solids
Dingxin Sun, Yi Chen, Gengkai Hu
Zero modes, which are deformations that cost zero energy, underlie many exotic behaviors in elastic metamaterials. While classical linear Cauchy elasticity explains many of these m…

Resonance-induced frequency splitting and evanescent modes at temporal interfaces in elastic metamaterials
Cong Chen, Kaijun Yi, Gengkai Hu
Temporal interfaces, defined by abrupt changes in material properties, break temporal translational symmetry and enable wave phenomena fundamentally different from those at spatial…
