摘要：

Novel features are predicted in the infrared absorption spectrum of an interacting electron gas in a parabolic quantum well with two characteristic curvatures (biparabolic quantum well). A series of well-defined absorption peaks appears below the frequency of the usual center-of-mass absorption. These subfundamental peaks correspond to modes of the coupled electron gas and light system, and lie beyond the usual treatment of light absorption within first-order perturbation theory.
