Quantum dots are fruitful systems for studying charge and spin dynamics at the single electron level. In this thesis we explore electron dynamics under strong microwave driving. This reveals a range of interesting non-equlibrium dynamics. We first study Landau-Zener-Stückelberg-Majorana (LZSM) dynamics in a single electron charge qubit. Here we observe the expected multi-photon transition fring...

Understanding the chemical cues and gene expressions that mediate herbivore-host-plant and parasite-host interactions can elucidate the ecological costs and benefits accruing to different partners in tight-knit community modules, and may reveal unexpected complexities. We investigated the exploitation of sequential hosts by the phytophagous-predaceous butterfly Maculinea arion, whose larvae ini...
