  Recent experiments have shown that Landau-Majorana-Stuckelberg-Zener (LMSZ)
interferometry is a powerful tool for demonstrating and exploiting quantum
coherence not only in atomic systems but also in a variety of solid state
quantum systems such as spins in quantum dots, superconducting qubits, and
nitrogen vacancy centers in diamond. In this work, we propose and develop a
general (and, in principle, exact) theoretical formalism to identify and
characterize the interference resonances that are the hallmark of LMSZ
interferometry. Unlike earlier approaches, our scheme does not require any
approximations, allowing us to uncover important and previously unknown
features of the resonance structure. We also discuss the experimental
observability of our results.
