Vortex light bullets in Rydberg atoms trapped in twisted $\mathcal{PT}$-symmetric waveguide arrays

|
By Junhao Li, Siliu Xu, Yiheng Hou, Jun-Rong He
| Physical Review B
We present a theoretical scheme for generating vortex light bullets (LBs) in a Rydberg atomic system. The stability property and propagation dynamics of vortex LBs with different topological charges are investigated in twisted circular waveguide arrays with a parity-time () symmetry. The numerical solutions of the corresponding nonlinear Schrödinger equation are obtained by the modified square operator method and split-step Fourier method.
