Photon statistics of the quantum emission of a metallic nanoparticle and quantum dot hybrid system — •Thorsten Sverre Theuerholz, Oliver Esser, Andreas Knorr, and Alexander Carmele — Institut für Theoretische Physik EW 7-1, Technische Universität Berlin, Hardenbergstr. 36, 10623 Berlin

Electrons in a metallic nanoparticle (MNP) exhibit collective oscillations with frequencies in the range of visible light. In our contribution, we derive the second order photon correlation function of a hybrid system made of a MNP and a semiconductor quantum dot (QD) driven coherently [1]. For this purpose, we treat the hierarchy problem by expressing the dynamical quantities in number states [2]. Within our theoretical framework, we discuss bunching and antibunching effects for the plasmons, depending on the frequency and intensity of the driving field.
