摘要：

We calculate the dynamical structure factor S(Q,omega) for correlated electrons in quantum dots in a magnetic field. The excitation spectrum of quantum dots, given by S(Q,omega), can be measured by electronic Raman scattering. By sweeping the magnetic field one should be able to observe the incompressible (large gaps in the excitation spectrum) and compressible (soft modes associated with phase transitions) electronic structure of quantum dots.
