School of Chemistry and Physics, University of KwaZulu-Natal, Durban 4001, South Africa(Dated: January 22, 2014)We consider the integration of quantum emitters into a negative permeability metamaterial design in order tointroduce tunability as well as nonlinear behavior. The unit cell of our metamaterial is a ring of metamolecules,each consisting of a metal nanoparticle and a two-level semiconductor quantum dot (QD). Without the QDs, thering of the unit cell is known to act as an artificial optical magnetic resonator. By adding the QDs we show that aFano interference profile is introduced into the magnetic field scattered from the ring. This induced interferenceis shown to cause an appreciable earXiv:1401.5402v1 [quant-ph] 21 Jan 2014 ect in the collective magnetic resonance of the unit cell. We find that theinterference provides a means to tune the response of the negative permeability metamaterial. The exploitationof the QD’s inherent nonlinearity is proposed to modulate the metamaterial’s magnetic response with a separatecontrol field.I. INTRODUCTION
