Optimal control of the local electromagnetic response of nanostructured materials: optimal detectors and quantum disguises

Abstract

We consider the problem of optimization of an effective trapping potential in a nanostructure with a quasi-one-dimensional geometry. The optimization is performed to achieve certain target optical properties of the system. We formulate and solve the optimization problem for a nanostructure that serves either as a single molecule detector or as a "quantum disguise" for a single molecule.
