Optical bright, dark and dipole solitons with derivative nonlinearity in the presence of parity-time-symmetric lattices.

This paper deals with the study of optical solitons in the presence of new linear and nonlinear parity-time (𝒫 𝒯) -symmetric modulation lattices. The nonlinear medium is a derivative term with arbitrary power. Inverse engineering scheme is utilized to retrieve bright, dark, dipole and singular soliton solutions. These solutions are presented for four new 𝒫 𝒯 -symmetric potentials. The results reveal that optical bright, dark and dipole solitons can exist for those new physical settings. [ABSTRACT FROM AUTHOR]
