Abstract
Confined indirect excitons in a two-dimensional magnetic lattice are promoted to simulate condensed matter systems. Excitonic particles are magnetically trapped so that a sufficient cooling mechanism can allow the trapped clouds of indirect excitons to experience the Bose-Einstein condensation phase transition. Thus, a long­ range spatial coherence can be resolved causing an inherited phase-locked across all of the coupled sites (single traps). Using an external magnetic bias field a mutual tunneling can adiabatically be exchanged between sites in which case the underline physics of Bose-Hubbard model can be explored such as Mott-insulator and Josephson Effect.
