Query: Optical Aharonov-Bohm effect in stacked type-II quantum dots   Excitons in vertically stacked type-II quantum dots experience the
topological magnetic phase and demonstrate the Aharonov-Bohm oscillations in
the emission intensity. Photoluminescence of vertically stacked ZnTe/ZnSe
quantum dots is measured in magnetic fields up to 31 T. The Aharonov-Bohm
oscillations are found in the magnetic-field dependence of emission intensity.
The positions of the peaks of the emission intensity are in a good agreement
with numerical simulations of excitons in stacked quantum dots.
