Interlayer Topological Transport and Devices based on Layer Pseudospins in Photonic Valley-Hall Phases
Xiaoxiao Wu, Zhenyu Li, Jian Chen +8
Valley-Hall phases, first proposed in two-dimensional (2D) materials, originate from nontrivial topologies around valleys which denote local extrema in momentum space. Since they a…
Symmetry-protected hierarchy of anomalous multipole topological band gaps in nonsymmorphic metacrystals
Xiujuan Zhang, Zhi-Kang Lin, Hai-Xiao Wang +5
Symmetry and topology are two fundamental aspects of many quantum states of matter. Recently, new topological materials, higher-order topological insulators, were discovered, featu…
Ultrafast cryptography with indefinitely switchable optical nanoantennas
Pujuan Ma, Lei Gao, Pavel Ginzburg +1
Bistability is widely exploited to demonstrate all-optical signal processing and light-based computing. The standard paradigm of switching between two steady states corresponding t…
Arbitrary order exceptional point induced by photonic spin-orbit interaction in coupled resonators
Shubo Wang, Bo Hou, Weixin Lu +3
Many novel properties of non-Hermitian systems are found at or near the exceptional points-branch points of complex energy surfaces at which eigenvalues and eigenvectors coalesce.…
Broadband microwave absorption by logarithmic spiral metasurface
Shubo Wang, Bo Hou, C. T. Chan
We propose to use logarithmic spiral resonators for efficient absorption of microwaves. By combining their scale invariant geometries and Fabry-Perot-type resonances stemming from…
Observation of second-order topological insulators in sonic crystals
Xiujuan Zhang, Hai-Xiao Wang, Zhi-Kang Lin +5
Topological insulators with unique gapless edge states have revolutionized the understanding of electronic properties in solid materials. These gapless edge states are dictated by…
Quantum-dot circuit-QED thermoelectric diodes and transistors

Recent breakthroughs in quantum-dot circuit-quantum-electrodynamics (circuit-QED) systems are important both from a fundamental perspective and from the point of view of quantum ph…
Second-order photonic topological insulator with corner states
Bi Ye Xie, Hong Fei Wang, Hai-Xiao Wang +4
Higher-order topological insulators (HOTIs) which go beyond the description of conventional bulk-boundary correspondence, broaden the understanding of topological insulating phases…
Valley kink states and topological channel intersections in substrate-integrated photonic circuitry
Li Zhang, Yihao Yang, Mengjia He +8
Valley degrees of freedom, providing a novel way to increase capacity and efficiency of information processing, have become an important instrument for photonics. Experimental stud…
Dynamically encircling exceptional points: in situ control of encircling loops and the role of the starting point
Xu-Lin Zhang, Shubo Wang, Bo Hou +1
The most intriguing properties of non-Hermitian systems are found near the exceptional points (EPs) at which the Hamiltonian matrix becomes defective. Due to the complex topologica…
Type-II Dirac photons at the metasurfaces
Chuandeng Hu, Zhenyu Li, Rui Tong +9
Topological characteristics of energy bands, such as Dirac/Weyl nodes, have attracted substantial interest in condensed matter systems as well as in classical wave systems. Among t…
Optical tristability and ultrafast Fano switching in nonlinear magneto-plasmonic nanoparticles
Wenjing Yu, Pujuan Ma, Hua Sun +2
We consider light scattering by a coated magneto-plasmonic nanoparticle (MPNP) with a Kerr-type nonlinear plasmonic shell and a magneto-optic core. Such structure features two plas…
Topological light-trapping on a dislocation
Fei-Fei Li, Hai-Xiao Wang, Zhan Xiong +6
Topology has been revealed to play a fundamental role in physics in the past decades. Topological insulators have unconventional gapless edge states where disorder-induced back-sca…
Nonlinear effects for three-terminal heat engine and refrigerator
Rongqian Wang, Jincheng Lu, Chen Wang +1
The three-terminal heat device consisting of a cavity and coupled to a heat bath is established. By tuning the temperatures of the electrodes and the phonon bath, the device can fu…
