Abstract

The time-dependent wave function of a nanoring driven by a laser field is obtained by exploiting the symmetriesinherent to the system and used for studying the properties of the electromagnetic radiation emitted by thenanoring as a function of the polarization state of the laser. The diffused radiation has the characteristics ofhigh-order-harmonic generation. For a noncircularly polarized laser field an extension of the expected cutoffposition is evident, indicating that nanorings are efficient sources of radiation. The polarization state of theemitted harmonics can be opportunely controlled by varying the parameters of the pump field. The profile ofthe absorbed angular moment shows that a magnetic moment can be induced depending on the polarization ofthe driven field.
