Title: Collisional Dynamics of Solitons in the Coupled PT symmetric Nonlocal nonlinear Schrodinger equations,
Abstract: We investigate the focusing coupled PT-symmetric nonlocal nonlinear
Schrodinger equation employing Darboux transformation approach. We find a
family of exact solutions including pairs of Bright-Bright, Dark-Dark and
Bright-Dark solitons in addition to solitary waves. We show that one can
convert bright bound state onto a dark bound state in a two-soliton solution by
selectively fine tuning the amplitude dependent parameter. We also show that
the energy in each mode remains conserved unlike the celebrated Manakov model.
We also characterize the behaviour of the soliton solutions in detail. We
emphasize that the above phenomenon occurs due to the nonlocality of the model.
