Abstract

We demonstrate an on demand spatial control of excitonic magnetic lattices for the potential applications of excitonic-based quantum optical devices. A two dimensional magnetic lattice of indirect excitons can form a transition to one dimensional lattice configuration under the influence of external magnetic bias fields. The transition is identified by measuring the spatial distribution of two dimensional photoluminance for several values of the external magnetic bias fields. The number of the trapped excitons is found to increase between sites along a perpendicular direction exhibiting two to one dimensional lattice transition. This work may apply for various controllable quantum simulations, such as superfluid-Mott-insulators, in quantum optical devices.
