In this work, based on the recently proposed (Phys. Rev. Lett. 110 (2013)064105) continuous nonlocal nonlinear Schr\"odinger system with parity-timesymmetric Kerr nonlinearity (PTNLSE), a numerical investigation has beencarried out for two first order Peregrine solitons as the initial ansatz.Peregrine soliton, as an exact solution to the PTNLSE, evokes a very potentquestion: what effects does the interaction of two first order Peregrinesolitons have on the overall optical field dynamics. Upon numericalcomputation, we observe the appearance of Kuznetsov-Ma (KM) soliton trains inthe unbroken PT-phase when the initial Peregrine solitons are in phase. In theout of phase condition, it shows repulsive nonlinear waves. Quiteinterestingly, our study shows that within a specific range of the intervalfactor in the transverse coordinate there exists a string of high intensitywell-localized Peregrine rogue waves in the PT unbroken phase. We note that theinterval factor as well as the transverse shift parameter play important rolesin the nonlinear interaction and evolution dynamics of the optical fields. Thiscould be important in developing fundamental understanding of nonlocalnon-Hermitian NLSE systems and dynamic wave localization behaviors.
