Rate-equation approach for multi-level quantum systems

Strong driving of quantum systems opens opportunities for both controlling and characterizing their states. For theoretical studying these properties we use the rate-equation formalism. The advantage such approach is its relative simplicity. We used formalism description a two-level system (TLS) with further expanding it on case multi-level system. Obtained results have good agreement experiments. presented can also be considered as one more way to explore underlying physical processes instance Landau-Zener-Stuckelberg-Majorana transitions interference.
