Topological semimetals with Riemann surface states
Chen Fang, Ling Lu, Junwei Liu +1
Riemann surfaces are geometric constructions in complex analysis that may represent multi-valued holomorphic functions using multiple sheets of the complex plane. We show that the…
An Invisible Metallic Mesh
Dexin Ye, Ling Lu, John D. Joannopoulos +2
We introduce a solid material that is itself invisible, possessing identical electromagnetic properties as air (i.e. not a cloak) at a desired frequency. Such a material could prov…
Three-dimensional topological photonic crystal with a single surface Dirac cone
Ling Lu, Chen Fang, Liang Fu +3
A single Dirac cone on the surface is the hallmark of three-dimensional (3D) topological insulators, where the double degeneracy at the Dirac point is protected by time-reversal sy…
Topological Phononic Crystals with One-Way Elastic Edge Waves
Pai Wang, Ling Lu, Katia Bertoldi
We report a new type of phononic crystals with topologically non-trivial bandgaps for both longitudinal and transverse polarizations, resulting in protected one-way elastic edge wa…
Spawning rings of exceptional points out of Dirac cones
Bo Zhen, Chia Wei Hsu, Yuichi Igarashi +6
The Dirac cone underlies many unique electronic properties of graphene and topological insulators, and its band structure--two conical bands touching at a single point--has also be…
Probing topological protection using a designer surface plasmon structure
Fei Gao, Zhen Gao, Xihang Shi +9
Topological photonic states, inspired by robust chiral edge states in topological insulators, have recently been demonstrated in a few photonic systems, including an array of coupl…
