Query: Controlling Coherent Quantum Dot Interactions   We measure many-body interactions in isolated quantum dot states using
double-quantum multidimensional coherent spectroscopy. Few states are probed in
a diffraction limited spot, which is enabled by a novel collinear scheme in
which radiated four-wave-mixing signals are measured with phase resolution.
Many-body interactions are enhanced by an additional prepulse tuned to the
delocalized quasi-continuum states. We propose this effect as a method for
controlling coupling between quantum states.
