Antichiral hinge states in a higher-order photonic nodal ring semimetal
Yuchen Peng, Deep Mondal, Yuting Yang +17
Antichiral states propagate in the same direction on opposite boundaries, defying the conventional constraint that boundary modes must cancel net chirality. Previously found antich…
Spin-to-orbital angular momentum conversion in non-Hermitian photonic graphene
Zhaoyang Zhang, Pavel Kokhanchik, Zhenzhi Liu +7
Optical beams with orbital angular momentum (OAM) have numerous potential applications, but the means used for their generation often lack crucial on-demand control. In this work,…
Dual phase transitions in a 1D lattice with PT-symmetric Floquet defect
Zhenzhi Liu, Ke Li, Yanpeng Zhang +1
Systems with non-Hermitian potential or Floquet modulation often result in phase transition related phenomena. In this paper, we study the dual phase transitions in a one-dimension…
Observation of nonreciprocal transverse localization of light
Shun Liang, Changchang Li, Wenqing Yu +7
Magnetic-free nonreciprocal optical devices that can prevent backscattering of signals are essential for integrated optical information processing. The achieved nonreciprocal behav…
