摘要：
We theoretically examine optical Aharonov-Bohm (AB) effects on trion and biexciton in the type-II semiconductor quantum dots. Many-particle states are calculated numerically by the exact diagonalization method. Two electrons in trion and biexciton are strongly correlated to each other, forming a Wigner molecule. The magnetoluminescence spectra from trion and biexciton change discontinuously as the magnetic flux increases by half of h/e, reflecting the Wigner moleculization.
