Abstract We employ the Hirota bilinear method to systematically derive nondegenerate bright one- and two-soliton solutions, along with degenerate bright-dark two- and four-soliton solutions for the reverse-time nonlocal nonlinear Schrödinger equation. Beyond the fundamental nondegenerate one-soliton solution, we have identified and characterized nondegenerate breather bound state solitons, with particular emphasis on their evolution dynamics. Furthermore, we have conducted a comprehensive analysis of the dynamic behavior exhibited by degenerate bright-dark soliton structures. These findings offer potential applications for nondegenerate and degenerate soliton interactions in nonlocal models.
