Higher-dimensional localized mode families in parity-time-symmetric potentials with competing nonlinearities

Dai, Chao-Qing; Wang, Yan


Both two-dimensional and three-dimensional localized mode families in different parity-time (𝒫𝒯)-symmetric potentials with competing nonlinearities are investigated. We show that localized mode families described by a (2+1)-dimensional nonlinear Schrödinger equation in the extended complex 𝒫𝒯-symmetric Rosen–Morse potential wells are unstable for all parameters due to the residue of gain (loss) in the system from the nonvanishing imaginary part in the extended Rosen–Morse potentials. In the...[Show more]
