Abstract: Abstract In this communication, we have constructed a generalized nonlinear Schrödinger equation based on nonlocal quantum momentum square operator. Single and bright singular combo solitons solutions have been obtained from quantum arguments. This study proves that solitons may be used to study nonlinear effects in nonlocal nonlinear media including nonlinear optics. Besides, it was observed that, near metal surface a quantum wire is governed, for particular kernels, by single electron symmetric soliton or a bright singular combo soliton depending on the nature of the potential energy originating from interaction of the electron with image charges in a quantum wire. These features are comparable to those soliton solutions arising in quantum optics and Bose–Einstein condensation.
