Exact Solution and Large-Scale Scaling Analysis of the Imaginary Creutz–Stark Ladder

We present an analytical solution for the complex spectrum of a Creutz ladder subject to an imaginary Stark potential. By mapping the system to a momentum-space differential equation, we derive the closed-form solution for the momentum-space wavefunctions. We identify a distinct cross-shaped spectru...
