Resumen
Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Motivated by the observation of multiphoton electric dipole spin-resonance processes in InAs nanowires, we study theoretically the transport dynamics of a periodically driven five-level system, modeling the level structure of a two-electron double quantum dot. We show that the observed multiphoton resonances, which are dominant near interdot charge transitions, are due to multilevel Landau-Zener-Stuckelberg-Majorana interference. Here, a third energy level serves as a shuttle that transfers population between the two resonant spin states. By numerically integrating the master equation, we replicate the main features observed in the experiments: multiphoton resonances (as large as eight photons), a robust odd-even dependence, and oscillations in the electric dipole spin-resonance signal as a function of energy-level detuning. 94 7 Gordon and Betty Moore Foundation's EPiQS Initiative [GBMF4535] National Science Foundation [DMR-1409556, DMR-1420541] Fapesp, Brazil INCT-DISSE/Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq), Brazil Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)
