Abstract
We propose a scheme to study loss-induced localization in a nonlinear three-site system with a periodically driven field acting on the first site and a loss on the last site. We identify a significant feature; that is, system losses could be introduced to profoundly enhance localization. Our simulation results present two different types of localization: chaos-related localization and loss-induced localization, depending on their physical mechanisms. These findings may deepen our understanding about the relations among nonlinear effects, system loss, and external driving fields and offer a fascinating route towards the potential application for quantum control of tunneling dynamics.
