Abstract:
This paper investigates the (2 + 1)-dimensional nonlocal Hirota–Maxwell–Bloch
(NH-MB) system under various types of nonlocality. The mathematical consistency of
possible nonlocal structures is analyzed, and three types that lead to a well-posed system are
identified. The integrability of the system is established through its Lax pair representation,
and a Darboux transformation is constructed. Exact soliton solutions are obtained for both
the defocusing and focusing cases. The results obtained may find applications in nonlinear
optics, quantum theory, and the theory of integrable systems.
