Tracking the mixing of single-particle states in correlated multi-particle complexes of quantum dots — •Diana Csontosová1,2 and Petr Klenovský1,2,3 — 1Department of Condensed Matter Physics, Faculty of Science, Masaryk University, Kotlářská 267/2, 61137 Brno, Czech Republic — 2Czech Metrology Institute, Okružní 31, 63800 Brno, Czech Republic — 3Central European Institute of Technology, Masaryk University, Kamenice 753/5, 62500 Brno, Czech Republic
By deconvolution of the Configuration interaction (CI) calculation of the electronic states in the quantum dots (QDs), we investigate (i) the content of single-particle states in multi-particle eigenstates of excitonic complexes, (ii) the heavy-light hole mixing in those, and (iii) their probability densities. Our approach enables us to track the aforementioned parameters for arbitrary size of the CI basis, i.e., including the effects of correlation. This provides us a way to find the most probable final states of excited trions or more precise determination of heavy-light hole mixing in the CI states. Our method enables a more precise study of the effects of tuning of emission properties of QDs using externally applied fields (electric, magnetic, strain).
