Real devices are never isolated, so we develop theory for quantum dynamics under dissipation, decoherence, and external driving. We build physically consistent reduced descriptions (from Lindblad generators to strong-coupling and nonequilibrium frameworks) that connect microscopic system-bath models to observable dynamics, including transport, relaxation, and irreversibility. A recurring theme is understanding when common approximations break down, especially in driven settings and nonequilibrium steady states, and deriving response theories and master-equation formalisms that remain predictive in experimentally relevant regimes.
