Evidencing non-Bloch dynamics in temporal topolectrical circuits
Maopeng Wu, Qian Zhao, Lei Kang +7
One of the core concepts from the non-Hermitian skin effect is the extended complex wavevectors (CW) in the generalized Brillouin zone (GBZ), while the origin of CW remains elusive…
A Knotted Meta-molecule with 2-D Isotropic Optical Activity Rotating the Incident Polarization by 90°
Wending Mai, Lei Kang, Chunxu Mao +7
Optical activity is the ability of chiral materials to rotate linearly-polarized (LP) electromagnetic waves. Because of their intrinsic asymmetry, traditional chiral molecules usua…
Chiral Balls: Knotted Structures with Both Chirality and Three-dimensional Rotational Symmetry
Wending Mai, Chunxu Mao, Lei Kang +3
Knots have been put forward to explain various physical phenomena because of their topological stability. Nevertheless, few works have reported on the exotic symmetry properties th…
Negative refraction at deep-ultraviolet frequency in monocrystalline graphite
Jingbo Sun, Ji Zhou, Lei Kang +5
Negative refraction is such a prominent electromagnetic phenomenon that most researchers believe it can only occur in artificially engineered metamaterials. In this article, we rep…
