Complex Spacetime Geometry as the Origin of Quantum and Electromagnetic Fields

The lack of a unified geometric foundation connecting quantum mechanics and electromagnetism remains a central challenge in theoretical physics. While quantum field theory treats particles as excitations of fields and general relativity describes gravity as spacetime curvature, a direct geometric link between quantum behavior and electromagnetic phenomena is still elusive. Motivated by this gap, we propose a novel theoretical framework that extends the Schrödinger equation into a complexified spacetime manifold. In this framework, spacetime is treated as inherently complex, with the real part governing classical evolution and the imaginary part encoding quantum fluctuations. By introducing complex derivatives that obey the Cauchy-Riemann conditions, we derive a modified Schrödinger equation whose structure naturally reveals the emergence of quantum behavior from imaginary curvature. Furthermore, we reinterpret the electromagnetic field as arising from the geometric curvature of the imaginary spacetime dimension. Specifically, we show that the imaginary part of the Ricci tensor yields structures mathematically analogous to Maxwell’s equations in curved space. The standard quantum commutation relations are also preserved under this complexification, ensuring compatibility with established quantum formalism. This unified approach not only preserves core quantum and electromagnetic features but also suggests that both phenomena are manifestations of a deeper geometric substrate. By embedding quantum mechanics and electromagnetism in a shared complex geometric framework, our results open promising avenues for a broader unification that may eventually incorporate gravity. This work lays a foundation for reinterpreting field interactions, quantum dynamics, and possibly spacetime itself through the lens of complex geometry.
