WebApr 9, 2024 · Rate-equation approach for a charge qudit. We theoretically describe the two-electron four-level double quantum dot (DQD) tunnel-coupled to a fermionic sea by using the rate-equation formalism. This approach allows to find occupation probabilities of each DQD level in a relatively simple way, compared to other methods.
