Defect solitons supported by nonlocal PT symmetric superlattices
Sumei Hu, Daquan Lu, Xuekai Ma +2
The existence and stability of defect solitons supported by parity-time (PT) symmetric superlattices with nonlocal nonlinearity are investigated. In the semi-infinite gap, in-phase…

Defect Solitons in Parity-Time Symmetric Optical Lattices with Nonlocal Nonlinearity
Sumei Hu, Xuekai Ma, Daquan Lu +2
The existence and stability of defect solitons in parity-time (PT) symmetric optical lattices with nonlocal nonlinearity are reported. It is found that nonlocality can expand the s…

Solitons supported by complex PT symmetric Gaussian potentials
Sumei Hu, Xuekai Ma, Daquan Lu +3
The existence and stability of fundamental, dipole, and tripole solitons in Kerr nonlinear media with parity-time symmetric Gaussian complex potentials are reported. Fundamental so…
