Symmetry-breaking bifurcations and ghost states in the fractional nonlinear Schrödinger equation with a PT-symmetric potential

Pengfei Li, Boris A. Malomed, Dumitru Mihalache

We report symmetry-breaking and restoring bifurcations of solitons in a fractional Schrödinger equation with the cubic or cubic-quintic (CQ) nonlinearity and a parity-time (PT)-sym…

Metastable soliton necklaces supported by fractional diffraction and competing nonlinearities

Pengfei Li, Boris A. Malomed, Dumitru Mihalache

We demonstrate that fractional cubic-quintic nonlinear Schrödinger equation,characterized by its Lévy index, maintains ring-shaped soliton clusters ("necklaces") carrying orbital a…

Symmetry breaking of spatial Kerr solitons in fractional dimension

Pengfei Li, Boris A. Malomed, Dumitru Mihalache

We study symmetry breaking of solitons in the framework of a nonlinear fractional Schrödinger equation (NLFSE), characterized by its Lévy index, with cubic nonlinearity and a symme…

Vortex solitons in fractional nonlinear Schrödinger equation with the cubic-quintic nonlinearity

Pengfei Li, Boris A. Malomed, Dumitru Mihalache

We address the existence and stability of vortex-soliton (VS) solutions of the fractional nonlinear Schrödinger equation (NLSE) with competing cubic-quintic nonlinearities and the…

Optical Solitons in PT-symmetric Potentials with Competing Cubic-Quintic Nonlinearity: Existence, Stability, and Dynamics

Pengfei Li, Lu Li, Dumitru Mihalache

We address the properties of optical solitons that form in media with competing cubic-quintic nonlinearity and parity-time(PT)-symmetric complex-valued external potentials. The mod…
