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…
