Analytical approach for pure high, even-order dispersion solitons
Xing Liao, Jiahan Huang, Daquan Lu +1
We theoretically solve the nonlinear Schrödinger equation describing the propagation of pure high, even order dispersion (PHEODs) solitons by variational approach. The Lagrangian f…
A variational approach to Schroedinger equation with parity-time symmetry Gaussian complex potential
Sumei Hu, Guo Liang, Shanyong Cai +3
A variational technique is established to deal with the Schrodinger equation with parity-time(PT) symmetric Gaussian complex potential. The method is extended to the linear and sel…
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…
Solitons in thermal media with periodic modulation of linear refractive index
Xuekai Ma, Zhenjun Yang, Daquan Lu +1
We address the existence and properties of solitons in thermal media with periodic modulation of linear refractive index. Many kinds of solitons in such optical lattices, including…
