Weyl points in three-dimensional optical lattices: synthetic magnetic monopoles in momentum space
Tena Dubček, Colin J. Kennedy, Ling Lu +3
We show that Hamiltonians with Weyl points can be realized for ultracold atoms using laser-assisted tunneling in three-dimensional optical lattices. Weyl points are synthetic magne…
Quantum Čerenkov Radiation: Spectral Cutoffs and the Role of Spin and Orbital Angular Momentum
Ido Kaminer, Maor Mutzafi, Amir Levy +7
We show that the well-known Čerenkov Effect contains new phenomena arising from the quantum nature of charged particles. The Čerenkov transition amplitudes allow coupling between t…
Structural Colors from Fano Resonances
Yichen Shen, Veronika Rinnerbauer, Imbert Wang +3
Structural coloration is an interference phenomenon where colors emerge when visible light interacts with nanoscopically structured material, and has recently become a most interes…
Optimization of sharp and viewing-angle-independent structural color
Chia Wei Hsu, Owen D. Miller, Steven G. Johnson +1
Structural coloration produces some of the most brilliant colors in nature and has many applications. However, the two competing properties of narrow bandwidth and broad viewing an…
Binary matrices of optimal autocorrelations as alignment marks
Scott A. Skirlo, Ling Lu, Marin Soljačić
We define a new class of binary matrices by maximizing the peak-sidelobe distances in the aperiodic autocorrelations. These matrices can be used as robust position marks for in-pla…
Topological Photonics
Ling Lu, John D. Joannopoulos, Marin Soljačić
Topology is revolutionizing photonics, bringing with it new theoretical discoveries and a wealth of potential applications. This field was inspired by the discovery of topological…
