An efficient framework for quantum dynamics driven by nonclassical light
Sheng-Wen Li, Zeyang Liao, Mao-Xin Liu
Understanding quantum system dynamics driven by nonclassical light pulses is challenging, particularly for general light states with large photon numbers. Here we introduce an effi…

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,…

Beam dynamics induced by the quantum metric of exceptional rings
Zhaoyang Zhang, Ismaël Septembre, Zhenzhi Liu +10
Topological physics has broadened its scope from the study of topological insulating phases to include nodal phases containing band structure singularities. The geometry of the cor…
