Higher-order exceptional point and Landau-Zener Bloch oscillations in driven non-Hermitian photonic Lieb lattices
Shiqiang Xia, Carlo Danieli, Yingying Zhang +6
We propose a scheme to realize parity-time (PT) symmetric photonic Lieb lattices of ribbon shape and complex couplings, thereby demonstrating the higher-order exceptional point (EP…

Free-space Realization of Tunable Pin-like Optical Vortex Beams
Domenico Bongiovanni, Denghui Li, Michail Goutsoulas +6
We demonstrate, both analytically and experimentally, free-space pin-like optical vortex beams (POVBs).Such angular-momentum-carrying beams feature tunable peak intensity and under…
