Description:
Author(s): Chandroth P. Jisha, Alessandro Alberucci, Valeriy A. Brazhnyi, and Gaetano Assanto Existence and stability of PT-symmetric gap solitons in a periodic structure with defocusing nonlocal nonlinearity are studied both theoretically and numerically. We find that, for any degree of nonlocality, gap solitons are always unstable in the presence of an imaginary potential. The instability ... [Phys. Rev. A 89, 013812] Published Mon Jan 13, 2014
